Rubber foamed sheet, or foamed board, is really a materials including cells inside. EPDM and PVC are two major kinds of foamed sheets.

EPDM (Ethylene-Propylene-Diene Monomer) foam rubber sheets consist of two types: the closed cell along with the open cell. The closed cell foam sheet has within itself independent little cells separated by cell membranes whilst in an open cell foam sheet, bigger cells are linked with one another.

The cells within foamed sheet incorporate air whose circulation is restrained, specially inside the closed-cell one particular, thus, this kind of a sheet can reduce the conduction of heat effectively. A low thermal coefficient, collectively with its organic softness and rebound resilience, helps make foamed sheet a perfect thermal-and-heat-insulation material vastly applied to car, shipbuilding, home appliances, electronic tools, health-related equipment, fitness gear, air conditioning and pipeline etc. For closed-cell foamed sheet alone, the separated cells, collectively with dewatering nature of rubber itself, avoid the water or moisture from percolation, and for this reason make closed-cell foamed sheet an ideal sealing materials. The EPDM foamed sheet is also of exceptional heat-resistance and weather-fastness and may function effectively at an temperature ranging from -60?? to upwards of 160??. Besides, its large fire resistance permits it to be used in the fields exactly where refractoriness is strictly demanded.

As what is identified to us, the sound is transmitted by means of air during the kind of vibration. Yet, when the sound wave bumps into a foamed sheet and clashes with all the cells full of air, its vibration will be hindered and weakened in strength and as a result the sound is decreased. This reality endows the foamed sheet another specific capability: sound-absorption, which, mixed with its softness, fire resistance and weather-resistance, tends to make it a whole new soundproofing materials.

Another widespread type of foamed sheet is PVC sheet, with PVC, or polyvinyl chloride currently being its major chemical composition. It’s produced from PVC, added with foaming agent, fire retardant and anti-aging agent, after which specific equipments are necessary to mold it into specific kinds. PVC sheet has found its way into many fields: developing, automobile and ship creating, furniture, decoration, advertisement and tourism, etc. You can find mostly two strategies to produce PVC sheet: crust foaming and totally free foaming. By crust foaming, the sheet is crusted to the surface, hence it’s a smooth skin; while by free foaming the sheet includes a pitted surface – rough and uneven without any crust. PVC foamed sheet might be compared favorably with wood for it may be sawn, planed, nailed and pasted. What’s more, it also possesses specific qualities such as non-deformation, non-cracking and its various colours saves it from painting. PVC foamed sheets are usually stable in chemical property and resistant to acid, alkali and corrosion. They are also moisture-proof, mildew-proof, and not easy to become worn by moth.

Despite the reputable assurance of PVC foamed sheet, you will find still worries, because instead of being a organic material, PVC is after all a chemical product, which is always labeled as toxic, malodorous and detrimental to environment. Nonetheless, the fact is far from being such negative. PVC sheet is totally non-poisonous and odorless and poses no threat to human skins or respiratory system, because the toxics have been fully eliminated from the raw materials of PVC, thus, the furnishings or kitchen wares packaged in PVC foamed sheet are proper choices for people who are allergic to wood or paint. Furthermore, if PVC foamed sheets are vastly employed as decorative materials, people can save huge number of woods – a contribution to the preservation of forests as well as the environment.
