heat stabilizer Sulfide Antioxidant , low odor dstdp for XLPE power
Quick Detail :
DSTDP is a dialkyl ester of thiodipropionic acid . It is used as a heat
stabilizer in combination with a phenolic antioxidant .
Name : DSTDP
CAS No . : 693 - 36 - 7
Chemical name : Tris ( 2 , 4 - ditert - butylphenyl ) phosphite
Use : stabilize polyesters , polycarbonates , polyamides ,
polystyrene , and elastomers . Use levels can range from 0 . 10 to
0 . 80 % based on the polymer .
DSTDP used in combination with a primary phenolic antioxidant
provides long-term heat stabilization to polymeric materials . With
the lowest volatility of all thio synergists , it combines
excellent performance with low odor .
