| Resin name |
Characteristics |
|
Polyvinyl chloride resin (PVC)
|
Soft products can be produced by the addition of a plasticizer. Chemical resistance, good electrical insulating properties (Low heat resistance. Gives off hydrogen chloride when heated) |
|
High-density polyethylene(PE)
|
Colorless and transparent; electrical insulating properties, good chemical resistance (Low solvent resistance, brittleness, low softening point) |
| Low-density polyethylene (PE) |
Crystalline resin, light weight, flexibility, electrical insulating properties, chemical resistance, water resistance, good heat-sealing characteristics (Poor printability and adhesive properties) |
| Polystyrene (PS) |
Good workability, electrical characteristics, water resistance; odorless and nontoxic |
| AS resin (AS) |
Transparent; high strength; higher heat resistance, weather resistance, and oil resistance than polystyrene (Slightly lower formability than polystyrene) |
| ABS resin (ABS) |
High toughness, high gloss, chemical resistance, high oil resistance |
| Methacrylic resin (PMMA) |
Colorless and transparent; weather resistance, good optical properties |
| Polypropylene (PP) |
More transparent, more resistant to repeated bending, and has a higher softening point than polyethylene (Poor printability and adhesive properties) |
| Polyamide (PA) |
Crystalline resin, high toughness, oil resistance, abrasion resistance, good gas barrier properties (High moisture absorption) |
| Polyacetal (POM) |
Crystalline resin; similar in properties to polyamide; high toughness, creep resistance, heat resistance, high solvent resistance
|
| Polycarbonate (PC) |
High toughness, electrical properties, heat resistance, excellent weather resistance; transparent |
| Denatured polyphenylene ether (PPE) |
High toughness, heat resistance, creep resistance, high steam resistance |
| Polybutylene terephthalate (PBT) |
Crystalline resin; heat resistance, electrical insulating properties, gas barrier properties, good chemical resistance |
| Polysulfone (PSF) |
High toughness, heat resistance, creep resistance, chemical resistance |
| Polyphenylene sulfide (PPS) |
Heat resistance, flame retardance, chemical resistance, electrical insulating properties |
| Liquid crystal polymer (LCP) |
High strength, high modulus of elasticity, thin-wall flowability, vibration characteristics, heat resistance, flame retardance |
| Resin name |
Characteristics |
| Phenolic resin (PF) |
Electrical insulating properties, strength, heat resistance, good durability (Dark, susceptible to alkali) |
| Urea resin (UF) |
Colorless and can be colored freely, similar to other phenolic resins, inexpensive (Inferior in heat resistance)
|
| Melamine resin (MF) |
Similar to urea resins, but has high hardness and good water resistance |
| Unsaturated polyester (UP) |
Lends itself to low-pressure molding, becomes tough when reinforced by glass fiber |
| Epoxy resin (EP) |
Have good adhesion to metals and minerals; electrical insulating properties, high chemical resistance |
| Silicon (Si) |
Electrical insulating properties, heat resistance, good water repellency; there are liquid, rubbery, and resinous types (Expensive) |
