(CH3)3C-O-O-C(CH3)2-(CH2)2-C-(CH3)2-O-O-C(CH3)3
Appearance£ºSolid, or gel,with slight
smell.
Quality Index:Peroxide Content¡Ý50%
Decomposing Temperature:145¡À20¡æ Temperature
from one minute after decomposing
Application:Accelerator DM-20 is
a vinyl vulcanize for silicic rubber at high temperature. It can be extremely
easily distributed and well mixed in silicic rubber with convenient process.
The vulcanized silicic rubber has even and stable physic performance,
high tensile strength and lancinating-resistant strength, small constant
deformation. Moreover, the end product has high transparency, excellent
yellowing-resistance, one-off vulcanization with no smell. Its quality
indexes reach or exceeds the similar products manufactured at home or
abroad. It is applicable to manufacturing such formed and mold-pressed
products as various silicic rubber key-press, sealing ring, accessories
in such industry as automobiles, heat-resistant rubber plate and silicic
rubber roller.
Application Method:
The amount of this product equaling to 1-5% of the weigh of mix-refined
gel (the standard quantity is 1.2% of the weight of mix-refinced gel)
is evenly added to the refining machine. After it is completely evenly
distributed in the refining process, it can be formed like flakes. Vulcanizing
Condition: 175-180¡æ¡Á2.5-5mm£¨Small mold-pressed product);The specific time
needed is decided according to the thickness, size, and filling amount
of each mold etc.
Package and Storage:
Packed in cardboard box lined with plastic bag with net weight of 15kg
per box; stored and transported according to the requirement for organic
peroxide, i.e. in dry, cool, ventilated, and faraway heat-and fire place.
Precaution:Please don't directly
contact it with eyes, mouth, and skin. If contacted in these parts, please
