Polyester resins, in thermoset, glass-fiber-reinforced formulations, have been used for a wide variety of engineering components since the early days of World War II. 

 

Meyer Plastics offers three main classifications of polyester materials:

 

PBT

PBT, or polybutylene terepthalate, is a high performance thermoplastic polyester.  It is a high-molecular-weight polymer with an excellent balance of properties and processing characteristics.  PBT has great resistance to a broad range of chemicals, high creep resistance and low moisture absorption.  Toughness is another strong point of the material.

 

PET / PETE

PET, or polyethylene terepthalate, is a high performance thermoplastic polyester.  It is a high-molecular-weight polymer with an excellent balance of properties and processing characteristics.  PET is a tough material that is resistant to a broad range of chemicals.  It also has high creep resistance and low moisture absorption.  The high stiffness of PET makes it suitable for structural applications.

 

PETG

PETG, or Polyethylene Terephthalate Glycol Modified, is a co-polyester thermoplastic.  It delivers impact strength that acrylic just can’t touch.  At the same time, PETG also provides many of the advantages of polycarbonate, but without the high material costs.  The benefits of PETG’s higher performance compared to acrylic, translate into thinner gauges and higher rates of production through easy die cutting, punching and low-temperature forming,
