Officinal pvc/pvdc coated film is firstly development and used by german factory in the 1940s. In practical application process, pvdc has good obstruct ability , it plays a good moisture-proof effect to the product in packing.
Pvdc material itself is the latex character, has quite big brittleness after the solidification. In the coating process and post-processing, the pivotal technical is to reduce its brittleness, make it normally used in the room temperature environment. Before, the technical ability is too poor to do so. That is one of the technical difficulties of pvdc compound material.
On the basis of oversea craft brother experience, our technician first produces successfully in china. It mainly takes pvc film as the basal material, then coated pvdc(import from basf in germany). During the production processing, the temperature, coated quantum, times and other important considerations are checked strictly to make sure that the product can meet the standard of the same product in the internatiolal. The obstruct ability is 5 times higher than common pvc. Meantime it has a certain rigidity, flexility and can be widely used in packaging various solid medicine, especially for easy humidity absorb medicine.
Remarks:
According to the investigation, presently 80% medicine using such packaging materials, but pvc film that widespread used in china could infiltrate the gas and liquor 6 months later in the boom temperature condition. It has a great impact on products. But if using pvdc, the period for protection can really reach at least 2 years.
This tape takes polyester as backing material and reinforced by fiberglass. There are two type of fiberglass tape: strip fiberglass tape and mesh fiberglass tape. It has more than 300lbs.In tensile strength, so it is used for insulation and heavy packing like washing machines, refrigerators, air-condition and metal and wooden furniture.
This tape takes polyimide film as backing material coated with imported silicone adhesive. It is high temperature resistant (grade h), acid and alkaline resistant, solvent resistant, radiation protection. It is applicable for the protection of pcb gold finger during the wave soldering under high temperature, high-class electrical and motor insulation and li batteries fixation, etc.
This tape takes imported glass cloth as backing material coated with imported silicone adhesive. It is high temperature resistant (grade h), flame retardant, solvent resistant. This tape is nearly same to 3m 69 glass tape. It is used for transformers and application for very high temperature environment.
This tape takes polyester film as backing material coated acrylic adhesive. It is high temperature resistance, solvent resistance and flame retardant. It is used for the transformers, capacitors.
The materials are quite accordance to the standard of environment protectlism. Applicate with advanced technology, excellent equipment, first-class products, we think, that must be satisfied to you at the most extent.
We are specialized in manufacturing electronic packaging materials such as smt tape smd tape top cover tape carrier tapes. We have new and advance technology so our products have many advantages. We got the certificate of sgs and iso9001. You can try our products. Plz feel free to contact us.
Application: available for mounting electronic parts on surface.
Advantage of top cover tapes:
The glueyness of product can be regulated in a large temperature range. It meets the requirement of smt very well. By imparting antistatic performance to the top tapes and bottom tapes, problems caused by static charges can be completely eliminated when mounting parts on surface.
The top tapes can be stripped on auto mounting neatly.
Product description:
The products use woven fiberglass mesh as base material, after coated with acrylic acid copolymer liquid then clean cut into different width and length tape. The chemical stability and no oxygenated property of fiberglass make the tapes have superiority that other materials can not be compared with. The products with good performances, like good softness, high stickiness, easy application, it gives you the best solution for the wall problems like wall crakes, plasterboard joints, wall holes etc, and it is the ideal material for dry wall and ceiling problems.
Filament winding roving is specially designed as reinforcements for thermoset resins used in filament winding processes. The size systems of filament winding rovings are made to achieve good compatibility with polyester, vinylester and eposy resins. It is soft, smooth and better compatible with styrene for resin impregnation. The grp is good property of water-resistance.
