Characteristics of each type of resin
PE

Polyethylene is a general-purpose resin that is used in a wide range of applications such as films.
It has low specific gravity, making it suitable for production of light products. It also boasts excellent impact
resistance, and maintains flexibility even at low temperatures. There are high-density polyethylene and low-density
polyethylene, with high-density polyethylene having excellent rigidity.

PP

Polypropylene, like polyethylene, is a typical general-purpose plastic.
Its properties are similar to those of polyethylene, but its specific gravity is even smaller, meaning it has the lowest
specific gravity among general-purpose plastics.
It has excellent mechanical strength, especially bending fatigue resistance.

TPO

TPO is a thermoplastic elastomer made by mixing and dispersing EPDM or EPM rubber in polyolefin resin(polyethylene/polypropylene).
It is a material that can be injection molded yet also has rubber elasticity. Its disadvantage being that it swells in
non-polar solvents such as aromatic organic solvents and mineral oils

Nylon 46

Nylon is generally an engineering plastic excellent in mechanical strength and heat resistance, and nylon 46 hashigh heat resistance, even among nylons, and is highly adaptable to high temperature environments.
It also has good chemical resistance but, as with all other nylons, has poor acid resistance.

PFA

PFA is a Fluororesin with excellent properties equivalent to polytetrafluoroethylene (PTFE).
It is also resistant to almost all chemicals, is non-stick, has low friction, and has very high heat resistance.
Moreover, it is flexible with high crack resistance. However, under high loads, caution against deformation isrequired.

PEEK

PEEK is a super engineering plastic with extremely high heat resistance and excellent strength at hightemperatures.
It has good wear properties and very good chemical resistance, except for sulfuric acid.
