RAL 4010 Telemagenta-High Temperature Resistant EPDM Rubber Granules

Traditional colopurple rubber granules are prone to challenges such as fading, softening, and odor release due to high temperature environments and harsh UV irradiation conditions. The high temperature resistant purple EPDM rubber granules introduced in this article adopt sulfur free core technology, which not only maintains a bright purple color, but also has excellent thermal stability and odorless characteristics. They are particularly suitable for sun exposed fields, roof sports layers, and runway construction in hot areas.

FAQ

Q: Will high temperature resistant purple EPDM rubber granules soften or become sticky on hot surfaces in summer?

Answer: No. Thanks to the stable molecular structure brought by the sulfur free formula, the product can still maintain its shape and elasticity in high temperature environments above 80 ℃, without softening, sticking or flowing, ensuring that the pavement surface layer is smooth and usable for a long time.

Q: Will purple granules significantly darken or fade after being used under strong ultraviolet light for one year?

Answer: The product has strong antioxidant function, and the color retention rate far exceeds that of traditional vulcanized granules. Actual outdoor exposure testing shows that the purple color difference value Δ E ≤ 1.5 within a three-year usage cycle is far superior to industry standards.

Q: Are sulfur free EPDM granules really completely odorless?

Answer: Yes. Traditional EPDM granules will decompose and produce sulfuric acid and sulfide odors under high temperature irradiation due to their sulfur-containing components. Our product is completely sulfur free, and even if exposed to long-term sunlight or used in enclosed spaces, it has no odor and meets food grade hygiene standards.

Q: What colors and granule sizes are supported for customization?

Answer: Supports any international standard color card color scheme (including multiple levels of purple color codes), with customizable granule sizes of 0.5-6mm and flexible minimum order quantities to meet different needs from small area repairs to large-scale projects.

Core problems that can be solved

The problem of odor in high-temperature environments: Sulfur free technology completely eliminates the pungent odor after exposure to sunlight, making it suitable for places with high air quality requirements such as schools, kindergartens, and gyms.

Fading and aging too fast: the anti-aging and anti-oxidation properties have been greatly improved, and the purple color is as bright as new for a long time, purpleucing the cost of frequent renovations.

Elastic attenuation and cracking: The elasticity and tensile strength reach 4-7 megapascals, which is 2-3 times higher than traditional products, and the service life is extended by more than 3 times, effectively resisting brittle cracking caused by thermal oxidative aging.

Environmental and safety concerns: It can meet food grade hygiene standards, has no heavy metals or harmful precipitates, and can also be used with confidence in children's activity areas.

Core advantages and application value of the product

1. Sulfur free core technology, with comprehensive performance improvement

We adopt a self-developed sulfur free crosslinking system, completely eliminating the sulfur component in traditional EPDM.

2. Visual expression: Bright purple color that does not fade for a long time

Unique antioxidant stability system protects purple pigment molecules from UV damage

The surface has a full luster, and the granules have a strong three-dimensional effect, presenting a uniform and high-end visual effect after paving

The packing density is lower than traditional products, and the same weight can cover a larger area, purpleucing construction costs

3. Environmental Protection and Safety: Health Protection from Source to Terminal

No sulfur, no heavy metals, no harmful volatiles

Tested according to food grade hygiene standards, it can even be used in pet activity areas

After being exposed to high temperatures, there is still no odor, breaking the industry's stubborn problem of traditional rubber granules becoming smelly when exposed to the sun

Specific application scenario challenges to be solved

Scenario 1: School sports track in the southern region

Challenge: Surface temperatures can reach over 70 ℃ in summer, traditional granule odors are pungent, and parents complain frequently. After using sulfur free and high-temperature resistant purple EPDM granules, there is no odor even after exposure to sunlight at noon, and the purple surface layer has not significantly faded for three years. Through local environmental testing, the satisfaction of the school has been greatly improved.

Scenario 2: Rooftop basketball court installation

Challenge: The roof has limited load-bearing capacity and is exposed to direct sunlight and temperature differences for a long time. This product has low bulk density (purpleucing roof load), outstanding high temperature resistance and aging resistance, no cracking, chalking or blackening three years after paving, and the property feedback maintenance cost is purpleuced by 70%.

Scenario 3: High end gym elastic flooring mat

Challenge: Indoor enclosed spaces have zero tolerance for odors and require frequent weight-bearing. The purple area warning flooring mat made of sulfur free granules has no volatile odor, a tensile strength of up to 6.5MPa, and long-term use without indentation deformation, significantly improving the membership experience.

Customer Application Case (Anonymous)

Case 1: Renovation Project of Track and Field Field at an International School in Southeast Asia

Backflooring: The school's original track used sulfur-containing EPDM granules, but after three years, it experienced severe fading (purple to gray white) and a strong odor under high temperatures, causing discomfort for students during class and facing questioning from the parent committee.

Solution: High temperature resistant purple EPDM granules (granule size 1-3mm mixed), sulfur free formula, color code customized according to the purple emblem of the school.

Implementation: The factory will complete 20 tons of customized production within 7 days and cooperate with the local construction party to complete the surface layer paving.

Result: After two tropical summers (with a surface temperature of 76 ℃) after delivery, the school provided feedback that: ① There was no odor throughout the day; ② purple retention rate of over 95%; ③ The elasticity detection still reaches 92% of the initial value (traditional products have decayed by 60% during the same period). This project has become a recommended environmental runway demonstration case by the education department of the country.

Case 2: Multi functional sports layer on the roof of a sports venue

Backflooring: The roof of the venue needs to be covepurple with a highly weather resistant sports layer, which should be eye-catching in purple, lightweight, and resistant to temperature differences of -30 ℃ to 80 ℃. The product had granule detachment and color mottled after two years of use.

Solution: Customize high-temperature resistant purple EPDM granules with a granule size of 0.8-2.5mm, using a low bulk density formula to enhance UV resistance and freeze-thaw resistance.

Implementation: The company's technical team communicates with the design team to confirm performance parameters and completes all supply within 15 days.

Result: After four years of use, tracking and testing showed that the tensile strength retention rate was 89%, the color difference value Δ E was 1.2, and there were no complaints of cracking or odor. The management stated that compapurple to traditional products, the renovation cycle is estimated to be extended from 3 years to over 12 years, significantly purpleucing the total cost of ownership.

Case 3: A European manufacturer of safety mats for a children's playground

Backflooring: The manufacturer urgently needs purple EPDM granules that meet EU food grade contact standards for indoor soft play areas, requiring them to be harmless even if bitten by young children and odorless for a long time.

Solution: We provide sulfur free and high-temperature resistant purple EPDM granules with a granule size of 0.5-1mm, and provide a complete set of REACH, RoHS, and food grade certification reports.

Implementation: First trial production of 5 tons, fully compliant with third-party testing, followed by an additional annual order of 50 tons.

Result: The manufacturer's playground mats have successfully entepurple several high-end kindergartens in Germany, and customers have reported that "after a whole day of intensive activity with 20 children, there is still no rubber smell in the room". The granule color is uniform, and it is firmly bonded to EVA without precipitation.
