First of all, they have different meanings:
1, meaning of epdm plastic track: EPDM plastic track has a colored rubber layer and a black rubber bottom layer, made of EPDM, and the track specification is 13mm.
2. Meaning of Silicon pu: Silicon PU is a kind of healthy professional elastic synthetic court surface material system which conforms to the ergonomic principle, meets the needs of sports physical characteristics, has the structural characteristics of hard top and elastic bottom, and can be directly constructed on the basis of cement or asphalt. One-component silicone modified polyurethane is used as the cushioning rebound structure, and two-component modified acrylic acid is used as the wear-resistant surface. Generally used as basketball courts, badminton courts and other sports venues.
Second, they have different characteristics:
1 and the characteristics of epdm plastic runway:
(1) Sunlight resistance and corrosion resistance: it can be used all day, and will not fade due to the pollution of ultraviolet rays and acid rain, and it can maintain its advanced quality for a long time.
(2) Flexible collocation of various colors: the colors are diverse and soft, and the grainy surface layer prevents the reflection of dazzling light, which is beautiful and durable, and multi-color collocation can be adopted.
(3) Strong wear resistance: the wear resistance is less than 2.5%, which can meet the needs of long-term and high-frequency use in schools at all levels.
(4) Damage resistance: it will not be damaged by spikes or the starting frame at the starting point of 100 meters with the greatest stress and the most frequent use.
(5) Simple maintenance: easy to maintain and save management costs.
2, the characteristics of silicon pu:
(1) Excellent weatherability: Silicon PU will not fade, harden, soften and turn white due to outdoor high and low temperature climate change, and it can keep bright color for a long time even under strong ultraviolet rays, ozone, rain and high temperature difference.
(2) Super wear resistance: the surface layer of silicone PU is made of silica particles, which has permanent and stable structural characteristics and moderate hardness, and the wear resistance can meet the requirements of long-term high-frequency use.
(3) Excellent pollution resistance: the surface layer of silicon PU is compact and its hardness is moderate. It is not easy to crack, peel, fade and turn white, and the stadium can be kept as clean as new for a long time through simple washing.
(4) Shock absorption: When the silicon PU bears instantaneous impact, 63% of the impact force is absorbed by the ground system, which better protects the athlete's ankle.
(5) Convenient construction: it can be directly constructed on the basis of asphalt concrete or cement concrete, and all materials are classified into barrels according to the proportion and constructed according to the instructions, so the operation is simple and convenient.
Extended data:
Efficiency of silicon pu:
1, stable and uniform rebound: Silicon PU has an innovative upper hard and lower elastic structure, and the hard surface layer has sufficient rebound support. With the help of the rebound characteristics of the elastic layer and the reinforcing layer, the rebound rate of the ball is ensured to be above 90%, which meets the requirements of professional sports for ball feeling, thus effectively solving the defects of PU soft surface such as ball trapping, ball sticking and uneven rebound.
2. Effective cushioning: Silicon PU is an elastic system specially designed for sports, which provides effective cushioning protection for sports. The elastic layer instantly absorbs the impact force through retraction, and the buffered pressure accumulates through the reinforcement layer to form an upward high resilience, effectively and slowly facing the sports injury caused by the reaction force of ankles, joints and ligaments.
3. Excellent anti-skid start: The silicon PU has a reasonably hard and rough surface designed according to ergonomics in sports, with moderate surface friction and elastic bottom structure, which provides sufficient friction for starting, changing direction, jumping and stopping in sports, effectively solving the skid phenomenon caused by wet surface and ensuring the comfort of feet in sports.
4. Comfortable directional movement: The innovative silicon PU hard surface layer provides sufficient physical foundation for smooth, multi-directional and fast movement in movement, and the lower layer realizes the reasonable structural transition from hard to soft by adjusting the modulus of elastic body, forming a professional movement structure with elasticity in hard but not soft.
