What's the difference between EPDM granules and TPV granules? 1. Chemical Composition & Structure
EPDM: This is a "thermoset" rubber. Once it is cured (vulcanized), its chemical bonds are permanent. It cannot be melted down or reshaped, which makes it harder to recycle. 2. Durability & Aging
Hardening: A common issue with EPDM is that it can become brittle and "rock-hard" over time due to UV exposure and oxidation. TPV is designed to maintain its flexibility and elasticity for a longer period, resisting the "brittle" phase that affects aging rubber. Wear Resistance: TPV generally has higher resistance to abrasion and tearing. In high-traffic areas like playgrounds or sports courts, TPV tends to hold its integrity longer without shedding granules. 3. Color Stability & UV ResistanceColor Fastness: TPV granules are often colored all the way through during the manufacturing process. This results in superior color retention. EPDM is also UV resistant, but it is more prone to slight fading or "chalking" over several years of intense sun exposure. Consistency: Because TPV is manufactured under more controlled thermoplastic processes, the color consistency between batches is often more precise than EPDM.
4. Installation & Aesthetics
Texture: TPV granules tend to have a smoother, more uniform shape, which can lead to a slightly "softer" feel underfoot, making it a popular choice for barefoot areas or premium kindergarten surfacing.
Binder Interaction: Both materials are typically installed by mixing the granules with a PU (polyurethane) binder. However, TPV’s chemical makeup allows for very strong adhesion with these binders, reducing the risk of the granules coming loose (granule loss). www.jiadongworld.com As the top manufacturer of EPDM granules and TPV granules, we will try to meet produce it as per the customer requirements. #TPV granules, #EPDM granules, #TPV granules maufacutrer, #EPDM granules manufacturer, #Poured in place TPV EPDM granules surfaces
