Every polymer has very distinct characteristics but most share a few similar characteristics. They are also major components of many formulated polymeric products such as coatings, adhesives, sealants, and grouts. The development of useful bio-composite materials requires that fiber-matrix adhesion is optimized to ensure good mechanical properties.

Polyester resins are known for their excellent combination of properties such as mechanical, thermal, chemical resistance as well as dimensional stability. 0000001564 00000 n When you want to apply any type of load on a particular member, you need to know its material properties, density, etc. Mechanically tougher Plastics come from polymers, hence all plastics are polymers, but not all polymers are plastic. The plastics that act as insulators mostly have a high dielectric strength. Plastics may be amorphous solids, crystalline solids, or semicrystalline solids (crystallites) or any other form of solids. 5.

Types of Plastics. %PDF-1.4 %���� Polylactic acid, or polylactide (PLA) is a thermoplastic polyester with backbone formula (C 3 H 4 O 2) n or [–C(CH 3)HC(=O)O–] n, formally obtained by condensation of lactic acid C(CH 3)(OH)HCOOH with loss of water (hence its name). So we say that materials like this are strong, but not very tough. It is a water-repellent plastic It is a water-repellent plastic PP has good resistance to environmental stress cracking For the most part, they are: Lightweight with a high strength-to-weight ratio Hydrolysis resistance 3. 0000001064 00000 n FRP composite materials possess superior mechanical properties including: It is important to under- stand these standard terms since they are used by sup- pliers and users to communicate how a material behaves under specific conditions. 0000001406 00000 n 0000002618 00000 n 0000000016 00000 n Mechanical Properties of Filler-reinforced Polymers. 0000007003 00000 n 0000014885 00000 n Depending on physical properties, plastics are divided into two types: Thermoplastic and thermosetting.
