White powder or granule
|
39-41°C
|
With DLTDP/PS800, good auxiliary antioxidant, has no pollution, no coloring, the characteristics of high temperature processing without decomposition.
|
Suitable for PE, pp, ABS, MBS, PVC and synthetic rubber, lubricating oil etc
|
DSTP

683
|
White powder or granule
|
65℃
|
With DSTDP/PS802, the antioxidant efficiency higher than DLTP, and volatility is low, small thermal loss.But the compatibility with resin as DLTP.
|
Suitable for polyethylene, polypropylene, polystyrene, ABS resin, polyester, nylon, PVC, pu, cellulose, plastics and synthetic rubber
