Low density polyurethane foam Products With molded process

There are many advantages to selecting Xingang PUR Foam.It exhibits excellent shock

absorption, high dynamic load capacity, excellent vibration dampening, noise reduction

and the highest modulus of elasticity of all elastomers. This high performance urethane

foam is SGS approved and has excellent abrasion and cut resistance. Our PUR foam also

performs well in oil and solvent environments.

So please tell us your production goals, the best polyurethane foam solution will be devised.

Paremeters

Density range : 160-180kg/m3

Applications: Home seals, such as Toilet gasket and kitchen room gasket.

Customized is ok, you send us request and production goals ,we will design and print the prototype. It has various kinds of color and size and hardness.

This size polyurethane flexible gasket has a Universal fit and is toilet seal with a wonderful

surface.

Many know how great a thing that is because if you use these PUR foam gasket and it

breaks, cracks or bends you can not use it and must start all over, for fear of not having

a tight enough fit.

The reaction makes all the difference.

Reaction injection molding and injection molding have almost the same name, so even experienced engineers and designers might think they are the same. But “Reaction” signals a big difference – unlike injection molding, RIM techniques utilize low-viscosity liquid polymers in thermoset – not thermoplastic – processes. Through a variety of chemical reactions, these polymers expand, thicken and harden only after they’re injected into the heated mold, accommodating much more intricate designs than ordinary injection molding. Raw materials and molding techniques can be selected and even customized to precisely deliver desired weight, strength, density and hardness characteristics. The result is large polyurethane parts with much lighter weight than those created by more commonplace processes.

The RIM Manufacturing process begins with polymer liquids (polyol and isocyanate) stored in large storage tanks and dispensed by large, high-pressure industrial pumps. The polymers are recirculated from the storage tanks to a multi-stream mix-head on the machined aluminum mold and back to the storage tanks in a continuous loop.
