<p>recycled materials and the use of foaming water or flammable propane or butane foam as a foam agent Low bulk density �� 30kg / m3, recycled materials, (old material) after repeated high temperature and pressure and shear Cut, the molecular chain is cut short, the molecular weight becomes smaller, the larger the rate of hole breaking, foaming film poor, poor hole, hole wall thickening, hardness increases, poor </p>
<p>flexibility, shorter product life, thermal insulation Thermal properties deteriorate. Breaking the product by hand, hard pinching does not rebound, resulting in product quality problems that affect the industry's right choice and use of XPS, low quality and low sales by no quality and credit guarantee. Some manufacturers choose to use relatively poor, with impurities in the recovery of materials, generally do not go through </p>
<p>filtration and processing, after milling use, blindly reduce costs caused by foam material containing impurities, reach the foaming rate and foam strength. Fire retardant generally non-flame retardant, easy to cause hidden dangers and insecurity factors, but also can not meet the user's effect and the use of standards. Market price of 280-320 yuan / m3. Third, the level of consideration XPS by industry grade. According to the </p>
