Poron is a microcellular polyurethane foam used in demanding shock-proof, sealing applications. Such as electronic products, auto parts and other industrial equipment. It is a high-quality foam, currently only the United States, Japan and other countries have the corresponding production technology, therefore, according to the difference in origin, directly called Japanese poron, the United States poron.
The hardness and internal strength of Poronfoam vary very little, and the thickness can range from 0.2 mm to 12.7 mm. Ultra-thin Poron can be used on ultra-thin products, effectively saving space.
The preparation method of poron and the polishing pad obtained therefrom, the method includes steps:
(a) The addition of a non-ionic surfactant to at least one of the components of a compound containing an isocyanate group and of a compound containing an active hydrogen group;
(b) stir and mix a mixture of the components and the components, adding a non-reactive gas to it;
c) pour the mixture out of the container at a predetermined rate;
(d) The poured mixture is injected into a mold to form the mold body in a predetermined shape.
1, with sealing, avoid gas release and atomization.
2 Compressive deformation resistance, that is, the elasticity is durable, and the accessories can be provided with long-term shock protection.
3, with flame retardant, does not contain harmful and toxic substances, will not remain, will not pollute the equipment, is not corrosive to metal.
4, can be used in a variety of temperature range. It can be used from minus 40 degrees Celsius to 90 degrees Celsius.
5, the surface has the infiltration, easy to stick, easy to make, easy to punch
6, engineered polyurethane formulations provide a wide modulus range - 2-90 psi @ 25% deviation - to meet more design flexibility requirements
