Product Definition

Two kinds of standards are usually used: British Standard and American Standard. In recent years, some customers have requested Canadian standards. The specific parameters are as follows:
British standard products meet the requirements of BS5852 Part2-Crib5
This product adopts imported flame retardants, Minaime and other additives to directly improve the flame retardant and fireproof performance of the product. It can endothermically decompose into non-flammable substances at or near the ignition temperature; it can react with foam combustion products to produce non-flammable substances; it can delay combustion and prevent smoke, causing the ignition site to self-extinguish. When burning, it releases white smoke, reducing pollution to the environment and reducing the emission of harmful substances.
American standard products comply with CAL TB-117A standard;
The fire-proof sponge adopts imported flame retardant, which can effectively reduce the burning time, delay the burning, and prevent the smoke from causing the fire part to self-extinguish. Usually the easiest way to test is for the sponge to self-extinguish within 6 seconds of leaving the fire.
Product introduction

Fireproof sponge, its chemical name is polyurethane foam material, is divided into two types: soft foam (mainly used for furniture) and hard foam (mainly used for heat preservation). The main raw materials are fire retardants, isocyanates, polyethers, polyols, etc. The auxiliary raw materials are a small amount of Freon, water, etc.
Product Features

Fire resistance: When the sponge burns, it will not produce an open flame.
Water resistance: closed cell structure, good water absorption.
Corrosion resistance: resistant to chemical corrosion such as seawater, oil, acid, alkali, etc., antibacterial, non-toxic, odorless, and non-polluting.
Processability: no joints, and easy to process such as hot pressing, cutting, gluing, laminating, etc.
Anti-vibration: high resilience and tensile strength, strong toughness, and good anti-vibration/cushioning performance.
Thermal insulation: excellent thermal insulation, thermal insulation and cold protection and low temperature performance, can withstand severe cold and exposure.
Sound insulation: closed cells, good sound insulation.
product category

Sponges are divided into three types: thin, medium and thick, which are divided into soft and hard:
1. Thin (1.0mm-8mm), used in packaging industry;
2. Medium (8mm-30mm), used in furniture and massage equipment industries;
3. Thick (above 30mm), used in the furniture and sofa industry.
Fire Sponge Hardness:
20-35°, soft sponge
45-60°, neutral sponge
60-70°, hard sponge
Above 70°, add hard sponge
Scope of application

Because of its thermal insulation, heat insulation, sound absorption, shock absorption, flame retardant, anti-static, and good air permeability, fire-resistant sponges are involved in various industries, including the automotive industry, pharmaceutical industry, cosmetics industry, special packaging manufacturing and high-end furniture. manufacturing, etc.
