Classification of thermoplastics

Chemical resistance

Crystalline resin

series Material name Chemical resistance
Olefin PE polyethylene Chemically stable and resistant to acids and alkalis
PP polypropylene
Ether POM Polyoxymethylene (Polyacetal) Strong against alkali but weak against acid flammable
POM/GF Polyoxymethylene (Polyacetal)
POM/CF Polyoxymethylene (Polyacetal)
Ketone PEEK Polyetheretherketone Excellent chemical resistance except hot concentrated sulfuric acid
PEEK/GF Polyetheretherketone
PEEK/CF Polyetheretherketone
Sulfide PPS Polyphenylene sulfide Excellent chemical resistance next to fluororesin
However, be cautious about oxidizing acids (nitric acid, sulfuric acid)
PPS/GF Polyphenylene sulfide
Ester PBT Polybutylene terephthalate Excellent corrosion resistance to acids
Easy to be hydrolyzed by alkali and hot water
PBT/GF Polybutylene terephthalate
Amide PA6 Polyamide 6 (Nylon 6) Excellent oil resistance
Slightly weak against acids and alkalis
PA6/GF Polyamide 6 (Nylon 6)
PA12 Polyamide 12(Nylon 12)
PA66 Polyamide 66 (Nylon 66)
PA66/GF Polyamide 66 (Nylon 66)
PA46 Polyamide 46 (Nylon 46)
MXD-6 Polymetaxylenediamine 6
(MX nylon Reny®)
Fluorine PVDF(2F) Polyvinylidene fluoride Excellent chemical resistance

Amorphous resistance

series Material name Chemical resistance
Olefin ABS Acrylonitrile / butadiene / styrene copolymer resin Pay attention to weather and heat resistance
Ether PPE Polyphenylene ether Strong against acids and alkalis, but weak against organic solvents
Low weather resistance, causing mechanical strength and color changes by ultraviolet light
PPE/GF Polyphenylene ether
Ester PC Polycarbonate Strong against acids but weak against water and alkali
Cracks occur when the load is applied continuously, and cracks appear more prominently when the temperature rises or the organic solvent comes into contact
PC/GF Polycarbonate
PC/ABS Polycarbonate polymer alloy
Sulfone PSU Polysulfone Non-hydrolyzing, resistant to acids and alkalis, resistant to heated steam
Poor stress crack resistance
Poor weather resistance, unsuitable for outdoor use
PSU/GF Polysulfone
PES Polyether sulfone
PES/GF Polyether sulfone
Imide PEI Polyetherimide (ULTEM®) Excellent acid resistance, oil resistance, hydrolysis resistance, and weather resistance
PEI/GF Polyetherimide (ULTEM®)
