(A) of polyvinyl chloride plastic (PVC)
PVC plastic is the main material of building plastics, by adding modifier can be made of soft PVC plastic, semi-rigid PVC plastic, rigid PVC plastic. Its products are sheet, coil, pipe, doors and windows profiles, decorative lines, such as feet and flowers. PVC flame resistance, as containing chlorine, so with self-extinguishing, non-combustion. PVC combustion release toxic hydrogen chloride gas, the flame was yellow-green.
(B) polyethylene plastic (PE)
PE is a polyolefin plastic, is divided into high, medium and low density polyethylene and chlorinated polyethylene. Its good flexibility, low temperature resistance, good impact resistance at room temperature resistance to solvent erosion is good, but the PE is easy to burn, the flame was light blue flame and dripping, which will lead to the spread of the flame. As a building decoration materials, PE products usually add flame retardants to improve its flame resistance.
(C) polypropylene plastic (PP)
PP is the smallest apparent density of plastic, and its combustion similar to the PE, heat resistance is better than PE, at 100 ℃ (and can maintain normal temperature tensile strength of 50%. Its mechanical properties better than PE, solvent PE and PP can be used to produce pipe, sanitary ware, chemical fiber carpets and so on.
(D) polystyrene plastic (PS)
PS is a transparent plastic, light transmission rate of up to 80% to 92%, soluble in toluene and other aromatic solvents. Add foam can be made of polystyrene foam, is an excellent insulation material. The main advantages are the small apparent density, water resistance, light resistance, chemical resistance, excellent electrical insulation; the main drawback is poor heat resistance, low impact resistance, brittle, flammable, burning yellow flame, and Release a lot of black smoke, leaving the fire to continue burning, issued a special smell of styrene.
(E) ABS plastic
ABS is a rubber modification of the PS plastic, also known as terpolymer plastic. Wherein A represents acrylonitrile, B represents butadiene, and S represents styrene. It has impact resistance, heat resistance, low temperature resistance, chemical resistance, dimensional stability, easy processing molding, the surface can be chrome plated and so on. By adjusting the proportion of the three components, access to a variety of properties of products, can be made with decorative patterns of decorative plate, ABS foam can replace wood, is a good building decoration materials. The disadvantage is not high temperature, flammable, weatherability is poor, opaque, modified by the treatment can be improved.
(6) Plexiglass (PMMA)
PMMA is the highest light transmittance of a plastic, up to 92%, it can replace the use of glass, and not easily broken, but the surface hardness than glass, easy to scratch. When the flame was light blue flame, the top white, no dripping, do not smoke, release monomer typical odor. It has excellent resistance to aging, in the tropical climate for many years its little change in transparency and color, can be used to make wall panels, lighting panels, advertising signs and so on.
(G) Unsaturated Polyester Plastic (UP)
UP is a thermosetting plastic, can be used to produce glass fiber reinforced plastic, polyester artificial marble. It can be cured at room temperature, easy processing, heat resistance, sound insulation, heat insulation, but not concentrated acid and alkali, the weather resistance depends on the formula.
(8) epoxy resin plastic (EP)
EP is a thermosetting plastic, before curing is a high viscosity liquid or brittle solid, soluble in acetone and xylene and other solvents. After curing agent can be added at room temperature or high temperature curing. Room temperature curing agent for diethylenetriamine, triethylenetetramine; high-temperature curing agent for o-dicarboxylic anhydride, liquid acid anhydride. EP outstanding performance with a variety of materials with a strong bond, it is in the curing shrinkage is very small, and in the occurrence of maximum shrinkage when the resin is still in a gel state, there is a certain mobility, it will not produce Internal stress. EP can be used as adhesive, paint sticky material, configuration putty, the production of glass and steel.
(Ix) Polyurethane Plastics (PU)
PU is a high performance thermosetting resin, it can be made into one-component or two-component coatings, adhesives, foam and so on. Depending on the composition, the PU may be soft or hard. PU performance, mechanical properties, aging resistance, heat resistance and so much better than PVC. As the architectural coatings used, its wear resistance, pollution resistance and anti-aging properties are good.
(10) Glass fiber reinforced plastic (GRP)
GRP, also known as glass fiber reinforced plastic, is a kind of thermosetting plastic reinforced with glass fiber products (yarn, cloth, chopped fiber, felt, non-woven fabrics, etc.) to enhance UP, EP and other resins. It is a composite material, through the glass fiber reinforced, high mechanical strength of reinforced plastic, its strength even higher than the steel. Can be used for the production of doors and windows, plates, tubes, profiles, travel lining, furniture and so on.
(11) Phenolic Resin Plastic (PF)
PF is a kind of hard and brittle thermosetting plastic which is not melted even when it is heated. It has the advantages of high strength, hard abrasion resistance, heat resistance, corrosion resistance, flame resistance, electrical insulation and moisture absorption. Also known as bakelite powder, is to create electrical insulation boards, pieces of raw materials. Laminated glass cloth can be made into laminated board.
