PORON product incorporates the following advantages:? Excellent resistance to compression set, sealing and cushioning properties it has long-lasting. ? Low outgassing and non-fogging, contain plasticizers or residual polluting chemicals. Material itself will not become brittle and broken, and does not corrode metal. ? With flame retardant properties of the material itself, did not use any additives. Much of the material to meet UL HBF and MVSS 302 prescribed fire retardant requirements. ? 2-90psi @ 25% deformation easy good chemical resistance, processing and cutting clean supply may be used with a variety of adhesives Korean PSR -?? Polyurethane formulations especially designed to provide a wide variety of design requirements modulus in the range of Foam phone manufacturers, foam manufacturers offer PSR Korea, South Korea PSR foam Details: Properties and Uses: ET slim one-piece high-density polyurethane foam slow rebound. Performance: super high impact shock drop test --- by telephone with high damping; thickness and dimensional stability - PET - integrally molded, thickness uniformity, under high pressure, at high deformation space still has excellent stability sex; green - does not add any polluting chemicals, and without the added material under any condition to maintain the dye moves good physical properties; Flammability --- PSR - NF PSR basic physical properties and consistent use Halogen-free materials certified by UL-94; high density and low compression set - sealing arrangement uniform pore cell structure of high-density foam, after prolonged pressure remain stable in prolonged by pressure still maintain the original structure intact. Purpose: LCD, microphone sounds surrounding - increased shading, absorb external impact, shock, filling space; vibration motor peripheral - shock absorbing motor and body, shock, increased air tightness; speakers, mobile phones, mini-phone peripherals - to prevent sound distortion, prevent sound flutter increased air tightness; shell surrounding - shock, maintaining spacing, increased air tightness; applicable aspects - the need to absorb the impact of the good performance of mobile communication equipment, computers, electro-acoustic products.
