Extruded foam silicone coil material is made of foamed silicone (traditional silicone density of 1.2, foamed silicone by foaming dilution will change its density similar to sponges), with the platinum vulcanization body, a set of production processes in the market, the vast majority of enterprises can not be produced, the circulation of products extruded foamed silicone coil is generally odorous (double two-four), the platinum + foaming combination of recommendations can be done directly after the FDA food grade requirements for food machinery and the need for FDA companies are big advantages. And extruded foam silicone coil in line with the FDA, national standards, Rors, halogen-free, REACH, California 65 and other third-party test reports, but also side by side to prove the advantages of its products.
Can be customized non-standard color without any influence, conventional bias color number can be customized production, and the next is the hardness of the product because food-grade extruded silicone foam coil belongs to the foaming process hardness is also from Shore A to Shore C hardness, and different hardness of its product performance parameters will change, this side of the hardness of the two 30 ° as well as 55 ° difference!
1. Food grade extruded foaming silicone rolls in the case of 30 ° hardness: the density is also relatively low, here to reiterate the density and hardness of silicone has a direct correlation between the hardness of the high density is also high, low density hardness is also low. So the density of food grade extruded silicone foam rolls at 30 ° is also in the 0.35 or so. Food-grade extruded silicone foam rolls at 50 °, the density can reach 0.55
2. Elongation at break and tear strength ≥ 250%, tear strength in ≥ 3KN / m, tensile strength ≥ 0.8Mpa, compression permanent deformation (180 ° * 168H * 35%) ≤ 10, the above for the food-grade extruded foamed silicone coil at 30 ° in all aspects of the performance parameters indicators.

3. In the food grade extruded foamed silicone coil to reach 50 ° when the performance parameters and will undergo significant changes, density 0.55, elongation at break ≥ 450%, tear strength ≥ 8.6KN / m, tensile strength of ≥ 1.6Mpa, compression permanent deformation ＜12, the above is the food grade extruded foamed silicone coil in 30 ° when all aspects of performance parameters indicators.
The above shows that food-grade extruded foaming silicone rubber coil and then the hardness of the rubber high performance parameters are also relatively excellent, are silicone unit price is based on the weight of the offer, the higher the density of its products will also increase the weight of the product, so the unit price will also rise, it can be said that food-grade extruded foaming silicone rubber coil performance parameters are also the influence of various aspects.
