Good UV radiation resistance for outdoor applications. However, UV stabilisers can reduce the impact strength. Advantages, disadvantgaes and applications are listed together with a table of typical properties for this thermoplastic.
Higher notched izod impact strength than other types of ABS. However has lower tensile strength and creep resistance. Advantages, disadvantages and applications are listed together with a table of typical properties for this thermoplastic.
Better tensile strength and creep resistance than high impact ABS. Advantages, disadvantages and applications are listed together with a table of typical properties for this thermoplastic.
These alloys are light weight, high strength and cheaper than zirconium containing nagnesium alloys. They find applications in the aeropsace, automotive industries as well as electronics, sporting goods etc.
By combining the bimaleimide system with epoxies, a new system was developed. It has increased the fracture toughness and the fracture energy with modest reductions in both the modulus and the glass transition temperature.
Heat treatment operations can be used to alter the properties of steels to suit an application. However, these processes may induce deformations unless guidelines are followed.
Techniques such as sheet moulding, pultrusion, filament winding, prepreg moulding and resin transfer moulding can be used to produce thermoset composites. These processes can be applied to a wide range of industries.
Plastic beer bottles made from PET offer numerous advantages over their glass counterparts. While they are not currently available, the advantages, disadvantages and technical issues are covered in this article.
