Good price High Styrene Rubber / HSR 60 / HSR 68 / HSR 80 / HSR 85
High styrene rubber is a special variety of styrene butadiene rubber. It is a non-polar polymer prepared from the co-polymerization of styrene and butadiene latex. Chemical structure:
—(CH2—CH=CH—CH2)m—(CHC6H5—CH2)n—
It is white granule, non-toxic, odorless and combustible. Heat distortion temperature: 70-90℃, white solid. It is used as filling reinforcing agent to improve the hardness, aging-resistance, wear-resistance, tear strength and tensile strength of rubbers. Has excellent thermoplasticity and electrical insulating propert
High styrene rubber is suitable forthe manufacture of high-hardness and low-density products.
1.Shoe-making: hard soles, heel, rigid foam sole, imitation leather shoes etc.;
2.As floor materials: rubber floor tile; industrial products, like rubber roll, washer, hard rubber tube and other sponge products;
3.Sports industry: balls, rollerskate;
4.Electrical insulating material;
5.High-grade bike cover tyre; various printing pastern roller; slab rubber;
6.ABS, AS plastic;
In recent years,rubber field are paying more attention to reinforcement of high styrene rubber,especially in the automobile industry,such as applied in the tyre.therefore,potential market of HSR is very huge. Our HSR can replace Japan's NIPOL HS850, HS860&HS870, JSR0060 and KER1904 and HS260 etc.
In high-strength composite bag lined with PE-coated woven bag/composite kraft paper bag, net wt. 20kg. Protect against fire, water and sunlight. Stored in cool and draughty place.
