PVB is the abbreviation of Polyvinyl Butyral. Pvb film is made from PVB resin and plasticizer. It is a non-toxic and smell- free soft sheet material with thickness between 0.2mm~2mm, the beat material for the interlayer of safty glass. it has four product property: 1. Safety, Snice the PVB films adhere tenaciously to the outer-layer glasses, laminated glasses for construction use become a good performance-effective safety glass material. Once the glass is destroyed, the glass scraps will still stick to the interlayer film and no damag will be caused on human beings and properties. Whether it is installed vertically or obliquely, laminated safety glass can alwwanys resist accidental impact and be safe from penetration. The glass will remain as a whole body after the first hit and can still resist further impact and tolerate harsh weather conditions.
2. Anti- penetration, Compared with other glass products, laminated glass interlayer films can ensure the safety of human beings and properties. Standard "sandwich" laminated glass is capable of resisting the penetration attempts of some common impacting materials. Even if the impact results in a hole, this hole will still be tiny enough. Once fragmented, the interlayer can still protect the building until it is replaced.
3. Anti-ultraviolet, PVB films shield ultraviolet lights to the greatest extent. It can block more than 99% of all the hazardous lights. This quality can protect furniture, hanging scrolls, displayed objects or other products from the harmful radiation of ultraviolet and avoid depigmentation.
4. Soundproof, The elastic PVB film in laminated glass has a resisting effect on sound waves. It can effectively reduce the annoying noise disturbance.
