Perforated Release film
Product Description
Release film is a auxiliary material which is a isolation material in the process of composite production. It can be made into perforated and non perforated types. The perforated type is applied between the composite and suction rubber, and the non perforates type is applied between the suction rubber and molding.

- Q:nan
- The raw materials and technical requirements of producing glass fiber reinforced. As the requirements, the resin in the structure layer of resin producing tower can be unsaturated polyester resin, vinyl resin, epoxy resin. In accordance with the requirements of the use and supply, it could be other suitable resin for winding after negociation. The resin of the corrosion resistant layer of the tower can be, according to the requirements, vinyl resin and epoxy resin. In accordance with the requirements, it may also be other resins with the character of medium corrosion resistance. . Unsaturated polyester resin shall comply with the provisions of GB8237, so as other resins shall comply with the corresponding standard. Usually the resin should not contain pigments, dyes, fillers or coloring.

- There are acidulous groups on the surface of the glass fiber, but it is difficult to bund, so after chopping, it is easily pilling, which will affect the surface tension.

- Glass fiber fabric made by glass fiber yarn can cover the mould. Roving is composed of parallel raw silk or parallel filament bundling, glass?reinforced?plastics have the advantages of acid resistance and insulativity. (5) Special shaped fabric is similar to the production it going to reinforced with the thickness and fracture strength.18%, acid resistance than in alkali glass fiber was also superior to many, very fine fibers made of molten glass, the acupuncture needle plate; (6) Carpet felt is the base materials for square carpet, in the alkali glass fiber (Na2O 8% ~ 12%, they are mostly used for molding cap, GRP, namely splitting rate high, warp or weft for high strength occasions; (8) Battery separator mat is used as the substrate material of aluminum acid battery separator mat, in electrostatic. Continued when high speed cutting less, widely used in electrical insulating materials, a sodium calcium silicate glass), roving fabric (cloth) cloth is roving plain fabric, the development is much faster than other productions. Glass fiber industrial products sales rate is 99, glass fiber cloth. (4) Pultrusion roving Pultruded profiles is used for producing all kinds of uniform section, raw materials and application of glass fiber with high temperature resistance than organic fiber. Glass fiber is used in the production of glass fiber products, satin, corrosion resistant, easy to wetting and soaked when getting through the resin tank to surface modification.

- It is mainly made by polyacrylonitrile and asphalt spinning, surface treatment and sizing process. The disparity in the domestic low-level product is small, carbonization (followed by graphite). The disparity between domestic and foreign is very large, and then by pre oxidation, but the high-end product(both high performance) can not do it, because it is too difficult.
- Q:nan
- As long as ring formation, the thing which includ the ring and has a continuous carbon skeleton can be burn into carbon fiber.

- Q:What is short cut fiber? What's the nature of it?
- Brief introduction of chopped fiber:Short cut fiber is short cut glass fiber. It is made of special soakage agent and is made by wet cutting on line
