Phenol resins are made from phenol and formaldehyde and mostly contain such fillers as wood meal, asbestos, craft paper and cloth. Molding will be a lot easier when being added with wood meal, […]
Urea resin can be produced through the reaction between urea ( ammonia) and formalin, catalyzed by acid or base. It is formed through compression molding adopting hard chrome plating model, […]
The substance is colorless and transparent, and can be colored freely, it is very hard and is of sound chemical resistance, water resistance, heat resistance, and fire resistance. […]
UP is the compound formed by the alkyd of unsaturated binary acid and ethylene monomer. The resin is a kind liquid of low viscosity, which will not produce gas when being solidified. Hence the molding pressure thereof is rather low. Intensified by glass fiber, it’s mechanical intensity will be much higher.
Major raw material for epoxy resin is reacted from propylene and benzene. The substance is adhesive to other substance, especially metals, and therefore, it can be made into adhesives. Another important feature is that it will not produce volatile substance when being solidified, and hence is of small shrinkage. Endowed with such advantages, it can [...]
Polyurethanes resin embodies the properties of foam, rubber, thermoplastic plastics as well as thermoset plastics, it can be used as elastomers, adhesives and coating etc and can also be adopted as synthetic fiber of large shrinkage. The substance is of high elasticity, obdurability and tensile strength, and can fight against the erosion from oil or [...]
The cellulose plastic is provided with high transparency and pliability as well as sound processability, fluidity and molding ability. The plastic has bright surface and sound dimension precision. It can be manufactured into fire resistance spectacles frame, tools, electric parts and transparent packing cases.
PC is a kind of colorless or primrose material, with high tensile strength, bending intensity, elasticity and impact resistance. These physical properties, almost equal to metallic materials, will not change dramatically with different temperature and the intensity can be retained under 140 celsius degree. […]
POM is a tough and strong material with sound heat resistance and solvent resistance. The property of POM is similar to nylon and PC, which is pretty strong and requires high thermal deformation temperature. In addition, […]
Nylons are generally tough and strong and boast high oil resistance and chemical resistance. They can be in stable use whether under high temperature or low temperature and hence possess excellent qualification for being used as engineering plastic. […]
