How much do you know about the role of polyurethane foam?

 

Polyurethane foam is a polymer material made from polyurethane raw materials through a special foaming process. It not only has the basic characteristics of light weight, softness, and good resilience, but also performs well in sound insulation, heat insulation, shockproof, and waterproof. Its core advantage lies in its excellent physical properties and chemical stability. It can maintain stable performance in extreme environments and is a filling, sealing, and buffering protection material in many fields.

Main features

It has excellent sealing properties to avoid gas release and atomization;

It has resistance to compression deformation, that is, the elasticity is durable, which can ensure that the accessories are protected from shock for a long time;

It is flame retardant, does not contain harmful substances, does not leave residues, does not pollute equipment, and is not corrosive to metals;

It can be used in a variety of temperature ranges. It can be used from minus 40℃ to 90℃;

The surface has excellent wettability, is easy to bond, easy to make, and easy to punch;

The engineering polyurethane formula provides a wide range of uses to meet more design requirements.

 

Main Applications

Panel interlayer: Function - no pollution, prevent looseness, prevent impact noise, prevent adhesion.

Around LED: prevent light leakage, absorb impact, and improve air tightness.

Around PCB: absorb impact, absorb vibration, fill gaps, and have heat insulation effect.

Keyboard gasket: rebound, no pollution, and good dimensional stability.

Around battery: no pollution, absorb impact sound, and improve air tightness.

Foot pad: good friction, no pollution, and good dimensional stability.

Drive tail pad: absorb vibration, prevent impact noise, and improve air tightness.

Friction pad: good friction, no pollution, and good dimensional stability.

Disk cover cushion: absorb vibration, block motor noise, shockproof, and improve air tightness.

Around speaker: prevent noise and fill gaps.

Around LCD: dustproof, absorb impact, fill gaps, and improve light shielding.

 

Selection Guide

According to application requirements: select polyurethane foam suitable for specific applications, such as electronics, automotive furniture, construction, etc.

Consider density and hardness: Choose the appropriate specifications of polyurethane foam according to the required density and hardness.

Durability: Choose durable and wear-resistant polyurethane foam to reduce maintenance costs.

Environmental protection: Choose environmentally friendly and non-toxic polyurethane foam to ensure safe use.

Cost-effectiveness: Consider cost-effectiveness and choose polyurethane foam with high cost performance.
