Product Introduction

We believe that in the market economy, competitors will always exist, and the only key to dominate the market is to improve the management and technical content of PU RUBBER SHEET, Zinc Borate 2335 80, Quazi MDI Three Componment Casting PU. Our enterprise tenet is, people-oriented, scientific management, explore users, seek development, safe and efficient, honest service. Taking science and technology as the guide, quality for survival, reputation for development of the enterprise purpose, everything is from the interests of users, user demand is the highest goal we pursue.

Cold casting two componment Polyurethane

- Composition: It consists of A&B component, A is polyol, and B is Hydroxyl-Terminated polyurethane prepolymer.

- Characteristics: It has excellent processing properties, solid in common temperature, shorter gel time, and regulating colours by adding pigment. The ware has good properties of abrasive resistance, hydrolysis resistance, transparent, good resilience, stable dimension.

- Product application: Rod and bar, sheet and plate, industrial wheel, construction mold, sports equipment coating, skateboard wheel, buffer insole and other polyurethane miscellaneous parts.

- Operation details: After vacuum degassing for the two components (A and B), they are mixing, pouring and casting in mold in proportion at room temperature of 30-40 ℃, it can be used for manual operation and mechanical molding.

- Storage: Store in a cool and dry place and use up as soon as possible after opening; It cannot be used up at one time, and it needs to be replaced with nitrogen and sealed; The secondary opening shall be used for defoaming, and the original storage period is six months.
