Function

PSBR is polymerized by butadiene and styrene, with good fluidity, coldness resistance, shock resistance, flexibilizer and other characters. Production can be divided into superior quality, first-class quality. According to the demand of the market, we can produce different grain size of PSBR.

Indicator

Appearance: white or yellow powder; styrene content: 23%; Mooney viscosity: 50-80; grain diameter: 40-80μm.

Application

(1)Can be used to modify resin such as PVC, PE, PP to improve their tenacity, shock resistance and so on.
(2)Can be used to mix and calendar in rubber production, such as rubber overshoes, rubber tube and so on.
(3)Brake pads, sealing materials and so on.
(4)Can be used to modify asphalt of road, water-proof roll material, emulsified asphalt, improve high and low temperature property, aging resistance, water-proof ability and increase service life.
