Common types of plastics and selection of adhesive

ABS: Common name engineering plastic, can be used for connecting parts, seat back, seat plate, it is the main raw material of plastic can be electroplated (water plating). The use of the automotive field includes the instrument panel, the exterior panel of the body, the interior decoration board, the steering wheel, the sound insulation board, the door lock, the bumper, the ventilation pipe and many other components. In electrical appliances are widely used in refrigerators, TV sets, washing machines, air conditioners, computers, copiers and other electronic appliances. In terms of building materials, ABS pipes, ABS sanitary ware and ABS decorative plates are widely used in building materials industry. In addition, ABS is also widely used in packaging, furniture, sports and entertainment supplies, machinery and instrumentation industries.

Adhesive ABS can be selected: quick drying adhesive, adhesive silicone (such as 704, etc.), acrylic AB adhesive has a certain corrosion. Epoxy adhesives have adhesive properties and may require surface treatment.

PP: Common name polypropylene, used for five-star feet, armrests, foot pads and connectors with low strength requirements. Disadvantages: poor wear resistance, low surface hardness. Such as plastic lunch boxes, garbage cans, water cups, buckets, basins and so on; Industrial supplies (mainly PP containing metal additives: fenders, ventilation pipes, fans, etc.), equipment (dishwasher door liners, dryer ventilation pipes, washing machine frames and covers, refrigerator door liners, etc.), consumer goods (lawn and garden equipment such as lawn mowers and water sprinklers, etc.)

Difficult to stick materials, usually adhesive parts are interface damage.

PVC: Common name polyvinyl chloride, mainly used for edge sealing, insert conditions. It is suitable for extrusion molding, and PVC material is a non-combustible material in plastic parts, and the temperature stability of processing molding is poor, especially the stability of color is not good. Typical uses water supply pipeline, household pipeline, house wall panel, commercial machine shell, electronic product packaging, equipment, food packaging, etc.

Generally with neoprene adhesive bonding, some need surface treatment,
PU: Common name polyurethane. Mainly used for handrail (foam) accessories. Building wall external insulation materials, wall insulation spray insulation materials

Refrigerator container freezer insulation, PU high imitation flowers, paper printing, cable chemical fiber, high-speed road surface, home decoration (corner line, retro background wall) furniture (imitation wood table and chair), foam filler, aerospace, automotive industry (sound insulation seal), sporting goods equipment (example: Boxing glove liner, Taekwondo foot guard, judo mat, etc.), synthetic PU leather, shoe industry, general paint, special protective paint, adhesive, etc

PUThey are easily bonded materials,Generally with adhesive glue can be bonded. Can be selected according to the working environment.

POM: Common name Saigang. Mainly used for wear-resistant parts such as foot pads, casters, door hinges, hinges and so on. Wear resistance, pressure resistance, but poor dimensional stability.
POM is an inert material, and it is generally selected as a quick-drying adhesive for bonding.  

PA: Common name nylon. Mainly used as foot pads, five star claws, casters and other wear-resistant, high life requirements. Features: wear resistance, pressure resistance, long indoor service life, individual models such as PA66 high temperature up to 2200, the disadvantage is that in the sun easy to change the performance, easy to break, poor weather resistance.
It is generally bonded with quick-drying adhesive.

PMMA: Plexiglass (commonly known as acacia). There are five kinds of transparent materials in plastic, and PMMA is one of the transparency, the workpiece has acetic acid taste when cutting, processing deformation is easy, and can be shaped and bent by soaking in boiling water. Disadvantages: The surface is easy to scratch, low hardness, easy to crack when bending, the price is more than 20% higher than ABS. Used to make transparent materials, such as lampshades.
Generally use epoxy AB glue, silica gel (704, etc.), light curing UV glue

PC: commonly known as polycarbonate. The variety is also a transparent material, with high surface hardness, scratch resistance, impact resistance, high strength, and good weather resistance (that is, not afraid of sunlight). Furniture screen partition sunlight board is this material hollow extrusion molding. Features: High price cost, about 40% higher than PMMA.

Generally use instant dry glue, 704 and other silica gel

PE polyethylene plastic, not easy to bond, generally with special instant dry adhesive adhesive.
