Polyurethane

Polyurethane For Thermoware

This product uses the HCFC-141B as blowing agent, which is the substitution of CFC-11 in polyurethane industry, it applies to refrigerators, icebox, coolers, hotpots, flasks and other thermal insulation products.

The characteristics are as follows, 

  1. Excellent flow ability, foam density distributes uniformity, low thermal conductivity
  2. Excellent low temperature dimension stability and cohesiveness
  3. Demould time 6~8 minutes

Polyurethane for Wood Imitation

Wood Imitation” structure foam , is a new type of carving synthetic materials . It has high mechanical strength and hardness, simple molding process , high production efficiency and excellent appearance.

Characteristics are as follows,

  1. Excellent repetition molding property.  It not only can mould certain shape size, but also for wood like structure and other designs.
  2. Appearance and feel close to wood , which could be planed, nailed, drilled, and carved patterns or designs .
  3. Mold can be aluminum or steel, and silicon rubber, epoxy resin or other resins, which are low cost and easy machining.
  4. Process is simple, fast, high efficiency of qualified.
  5. Physical and mechanical properties is one of optimal synthesis wood produced by various polymer . Physical property can be controlled by adjusting the formula.
