2、Application characteristics of thermoplastic rubber sebs-yh501 / 501t
Yh-501 is a low molecular weight linear SEBS, which has the characteristics of good fluidity and low solution viscosity. It can be used in the production of hot-melt (pressure-sensitive) adhesive and plastic modification.
The hot-melt pressure-sensitive adhesive has the characteristics of moderate initial adhesion, peeling force and good cohesion. It can be used in the production of packaging protective film, etc; Adding an appropriate amount of SIS into yh-501 can effectively improve the initial adhesion and peel strength of its hot-melt pressure-sensitive adhesive, and can prepare high-performance pressure-sensitive adhesive. The hot-melt adhesive produced by yh-501 has the characteristics of good fluidity, good creep resistance, aging resistance and high cohesion strength. It can be used to produce the back adhesive of high-grade carpet and anti-skid floor mat; It can also produce hot melt adhesive for bonding wood, paper, fiber fabric, leather, metal and plastic.
