High-strength, flexible, and extremely excellent in wear resistance, this urethane rubber also has chemical resistance and serves effectively as a vibration-damping material for storage batteries!
"HapraCast EL" is a urethane casting material for elastomers (urethane rubber). It allows for a wide range of products with a hardness of 40 to 90 Shore A. The main agent (polyol component) and the curing agent (isocyanate component) are mixed in two parts and cast into a mold. It has been developed as a product for MDI and polyol curing. (It does not use any conventional toxic substances such as TDI or MOCA, which fall under specific regulations.) 【Features】 ◆ Unique vibration-damping performance While hard, it has a high tan δ of 0.1 or more ◆ Extremely high safety Does not use MOCA or TDI ◆ High physical strength Chemical resistance, abrasion resistance, high mechanical properties, flexibility *For more details, please contact us or refer to the catalog.

Company information
We develop, manufacture, and sell our own polyurethane resin. Our product range is diverse, and we develop and sell unique products that cannot be found from other companies. At our company, we can provide one-of-a-kind products by developing and formulating resins from scratch based on the needs we receive from our customers. If you have any concerns such as "Can we create this type of resin?", "I want to create a unique product that stands out from competitors", or "I want to use new materials even in small quantities", please feel free to contact us. Our company focuses on "polyurethane gel", a soft material that cannot be achieved with rubber, which is particularly used in many vibration-damping materials. We uniquely design resin formulations tailored to the vibrations you are facing. Additionally, "polyurethane resin" can be shaped into various forms beyond rubber, such as paints, plastics, and foams, allowing us to develop and sell unique products like: - Stretchable paint - Plastic that turns into a clay-like substance in response to heat - Plastic that hardens in 90 seconds when two components are mixed - Foam that rebounds over 80%
