Pre-dispersed foaming agent OBSH-75
The pre-dispersion of organic foaming agent for rubber can start foaming OBSH-75 at 150 ℃ and release N2. Adding appropriate foaming active agent can further reduce the initial foaming temperature, and reasonable design and reasonable matching of foaming speed and vulcanization speed can improve the foaming quality. Thermoplastic EPDM/EVA as an effective pre-dispersion carrier can promote OBSH rapid mixing and uniform dispersion.
Key words:
TAC can significantly improve the strength, rigidity and heat resistance of plastic products, and can make the products use for a long time at about 250 ℃. Therefore, it is a new crosslinking agent for the preparation of high-performance unsaturated polyester, acrylic series resin products. Especially suitable for the preparation of high temperature resistant, high strength FRP products; can also be used in rubber, cable industry, do highly saturated rubber vulcanization accelerator, improve the vulcanization effect; can also be used to do polyene irradiation crosslinking photosensitizer, reduce the amount of exposure.
Key words:
Can be used as a single component, can also be used as a methylene donor with methylene recipient, improve the adhesive strength of rubber and skeleton.
