Polyurethane rigid foam is a rigid foam material made of polyurethane foamed by a specific process. This material is not only hard in texture, but also has excellent resistance to permanent compression deformation. It can effectively resist external vibration and impact. Even in extreme temperature environments, polyurethane rigid foam can still maintain its original integrity and effectiveness. It has become a buffer material in the fields of gasket design, sound insulation and heat insulation.

There are many types of polyurethane foam. Including soft polyurethane foam, soft polyurethane foam, fast rebound polyurethane foam and hard polyurethane foam. Each foam has its own unique properties and application scenarios. But hard polyurethane foam has its excellent physical properties. It is widely used in various precision products for shockproof and other purposes.

 

Main features

It has excellent sealing performance to avoid gas release and atomization.

Compression deformation resistance, that is, elasticity is durable, which can ensure long-term shock protection of accessories.

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 -40 degrees Celsius to 90 degrees.

The surface has excellent wettability, easy to bond, easy to make and convenient for punching.

The engineered polyurethane formula provides a wide modulus range - 2-90psi@25% deviation - to meet more design requirements.

 

Main uses

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

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

Around the lower periphery of the PCB: absorb impact, absorb vibration, fill gaps, and have heat insulation effects.

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

Around the 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 gasket: good friction, no pollution, and good dimensional stability.

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

Around the speaker: prevent noise and fill the gap.

Around the LCD: prevent dust, absorb impact, fill the gap, and improve light shielding.

 

Storage matters

Keep dry: avoid humid environment to prevent foam deformation.

Reasonable stacking: avoid heavy pressure to ensure that the foam shape remains unchanged.

Avoid high temperature: store in a cool place and avoid direct sunlight.

Prevent pollution: avoid contact with harmful substances to ensure foam performance.

Regular inspection: check the storage status regularly to ensure that the material is not damaged.

Follow the advice: store according to the product instructions to extend the service life.

 

Selection guide

Clear requirements: determine the required performance parameters according to the application scenario.

Performance requirements: select appropriate performance indicators according to actual needs.

Density selection: Foams of different densities have different performance.

Consultation: If you are not sure, it is recommended to consult professionals for advice.

 

Polyurethane rigid foam is a high-performance foam material. It is processed into auxiliary parts of various shapes and sizes through precision die-cutting equipment. Die-cutting is a precise and efficient cutting process. It can ensure that the product edges are smooth and free of residue. And it can ensure that every die-cut product can meet strict quality standards. It is widely used in many fields such as electronic products, automobile manufacturing, and construction industry. It provides buffer solutions for all walks of life.
