Advantages of cost of custom cut polyurethane foam
High-density sound absorption
Open-cell foaming forms a sound capsule with high density sound absorption. When the sound wave enters the sound-absorbing pores, it will vibrate and rub against the pore wall to convert the sound energy into heat energy,
which is then absorbed
5cm high density
The polyurethane foam manufacturing process ensures high-weight honeycomb sound insulation holes for excellent sound insulation and noise reduction.
Good resilience and high density
Not easy to break, reducing construction consumables, durable and wear-resistant, more cost-effective
B1 flame retardant self-extinguishing
Polyurethane environmentally friendly sponge, multiple tests have B1 flame retardant performance.
Self-extinguishing test
The product will extinguish itself when it is away from the fire. Flame retardant does not mean it will not burn, but it can effectively slow down the burning speed
Self-extinguishing after 3s
Strong flame retardant performance, prevent safety hazards and prevent them (Note: Do not burn the product in open flames for a long time
Waterproof and oilproof
Non-absorbent, porous, and closed foaming properties make high density PVC foam sheet resistant to liquid penetration.
Moisture-proof test
Closed-cell foaming structure refines the foaming pores and locks in water in a closed loop, enhancing PVC rubber sheet sound insulation.

polyurethane foam Material Introduction
Polyurethane sponge is a porous sponge material made by the reaction of polyisocyanate and polyol.
Characteristics and classification
Polyurethane sponge has excellent insulation properties and is easy to form.
According to the density of the foam, the softness of polyurethane sponge can be adjusted. Low-density sponge is soft and has good cushioning properties.
Polyurethane sponge is divided into two categories: soft and hard, which can meet the needs of different application scenarios.
