PORON PORON foam is a fine uniform cell structure of high-performance polyurethane foam material, generally divided into PET and non-PET with two kinds. Specifications are: SR-S-24P SR-S-40P ASRS-32PA SR-U-40PSR-S-32P SR-S-48P MS-40P SR-S-48P SS-24P MH-48PSR-S70PA SS-32P MS -40 ML-32 MH-32 H-32 HH-48FH-48 MH-32 MX-48HF H-48 HH-48C FH-48C MO-48, more commonly used model is HH48C, L32, H48, L24, H32. Key Features: 1, excellent sealing, deformation is very small, sealed high, to avoid the release of gas outside and fogging. 2, excellent resistance to compression set, good energy absorption, recoil and strong, that elasticity is persistent, long-term, guaranteed parts of shock protection. 3, flame retardant, does not contain harmful toxic substances, will be left without pollution equipment, non-corrosive metal. 4, weather aging resistance, can be used in a variety of temperature ranges. It can be used from within a range from 40 degrees Celsius to minus 90 degrees. 5, the surface has excellent wettability, easy bonding, easy to make, easy punching. 6, engineering polyurethane formulation provides a broad range of modulus - 2-90 psi @ 25% deviation - more design flexibility to meet the requirements of the main uses are as follows (1) sandwich panel: the role of - pollution, prevent loosening, to prevent impact noise, prevent sticking. (2) LED around: to prevent light leakage, absorb shock, worry high air tightness. (3) PCB under the surrounding: absorb the impact, absorbing shock, to fill the gap, insulation effect. (4) keyboard pads: rebound good, clean, dimensional stability. (5) Battery around: pollution, absorb impact sound and improve air tightness. (6) Feet: frictional good, clean, good dimensional stability. (7) drives the rear pad: absorb shock, prevent impact noise, improve air tightness. (8) Friction pads: frictional good, clean, good dimensional stability. (9) The pan cover cushion: vibration absorption, interdiction motor noise, vibration and improve the air tightness. (10) speakers around: to prevent noise, to fill the gap. (11) LCD around: dust, absorb shock, to fill the gap and improve the blackout Note: according to customer requirements coating, composite, slitting, punching (using a mold of the specified material cut out the desired shape to match customers Demand during assembly) Tips: The above price are for reference, not real quote, the actual quote will be based on the actual dimensions to offer, the company has its own R & D department, according to customer samples to map processing, can complete the design, slitting, laminating, die cutting workflow. Welcome customers to visit or call to discuss plans to sample.
