ETHYLENE VINYL ACETATE (EVA)
CAS Number : 24937-78-8
Formula : (C2H4)n(C4H6O2)m
APPLICATIONS
-
EVA is applicable for a number of different end-uses such as flexible packaging, heat seal layers, thermal laminations, hose & tubing, blow molded bottles and cap liners etc.
-
As EVA resins can be easily cut from sheets and molded to any desired shapes they are being used to produce complex end-user goods also.
-
It is applicable to be used for orthotics, cigarettes, surfboard, skim boards and even manufacturing artificial flowers.
-
They are even used for thermoplastic mouth guards and conditioning or waterproofing leathers.
Ethylene Vinyl Acetate is a flexible and transparent thermoplastic. It shows good chemical resistance. EVA shows good barrier and stretch properties. It also offers good low temperature flexibility.it is used in several due to the varied properties it possesses.

POLYETHYLENE TEREPHTHALATE
(PET RESIN)
CAS Number : 25038-59-9
Formula : (C10H8O4)n
APPLICATIONS
-
The largest outlet for PET is for the production of synthetic fibres with bottle resin.
-
Polyester is the largest synthetic fibre used in the world with production split roughly 60/40 between polyester filament and polyester staple. Filament yarns are used in clothing, furnishings, tyre cord and technical textiles.
-
PET is used as a 3D printing filament, as well as in the 3D printing plastic PETG.
-
PET film is often used in tape applications, such as the carrier for magnetic tape or backing for pressure-sensitive adhesive tapes.
PET in its natural state is a colorless, semi-crystalline resin. It shows excellent resistance to alcohols, aliphatic hydrocarbons, oils, greases and diluted acids. It is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods.

POLYVINYL CHLORIDE RESIN
(PVC RESIN)
CAS Number : 9002-86-2
Formula : (C2H3Cl)n
APPLICATIONS
-
Around 50% of PVC (or vinyl) manufactured is used in construction replacing other materials such as wood or glass. Cheap, resistant, good weather ability.
-
PVC is strong, lightweight, durable and versatile. These characteristics make it ideal for window profiles. PVC's inherent flame retardant and excellent electrical insulation properties make it ideal for cabling applications.
-
It is also used in the medical sector due to its safety and chemical stability and bio-compatibility, chemical resistant and low cost. In addition, it is usable inside the body and easy to be sterilized.
-
Typical examples of PVC automotive components include: moldings, interior door panels and pockets, seat coverings, sun visors, seals, floor covering, wiring, exterior side molding and protective strips, anti-stone damage protection, etc
