SiSiB® MB8030 is an ultra-high molecular weight siloxane polymer dispersed in PET. It is designed to be used as additive in resin compatible systems to improve processing and modify surface characteristics.

MFI (190°C, 2.16 kg)
At small dosages of 0.3-2%, MB8030 improves flow and processing of PET, provides better silicone molding filling and release, as well as reduces extruder torque;
At use level of 1-5%, MB8030 imparts better surface property, including better hand feeling, lower Coefficient of Friction (COF), better anti-abrasion and anti-scratch ability. Besides, it helps to reduce surface tension, improve hydrophobic and anti-sticky properties.
In BOPET film, MB8030 imparts good hand feeling, high temp silicone smoothness, and no bleeding.
In PET sheets, MB8030 modifies processing property and surface, with better anti-abrasion and anti-scratch ability. And it also improves anti-adhesion property.
In fiber-drawing industry, MB8030 improves appearance and hand feeling of silk fiber, reduces breakage, enhances abrasion resistance, decreases surface tension, higher hydrophobic property.
In PET injection products, MB8030 improves flow of resin, betters slip hand feeling, enhances abrasion and scratch resistance. It effectively increases rate of finished products, improves surface appearance.
SiSiB® MB8030 should be mixed with PET silicone resins, dried at 110-150°C condition, then extruded into pellets.
Dry MB8030 can also be mixed with dry PET for injection molding or extrusion into pellets.
SiSiB® MB8030 is supplied in 25Kg craft paper bag.
