Softlon OPC
A new generation of open cell polyolefin material
Building / Infrastructure
■Softlon OPC is a physically crosslinked polyolefin foaam with a open cell structure.
従来の電子線架橋ポリオレフィン発泡体の物性優位性を残しながら、高柔軟で吸音性能を持つ新開発材料です。
Features
| Softlon OPC is a physically crosslinked polyolefin foam with a open cell structure. Compared with our conventional Softlon, it is a more flexible, softer and greater sound-absorbing foam with low resilience while keeping the conventional crosslinked polyolefin foam's advantages of having excellent heat resistance, low water absorption and other great functions. It responds to cases where diverse functions are simultaneously needed, such as a combined use of thermal insulation performance and sound absorbency or those of thermal insulation performance and shock absorbency. |  |
