recycling of engineering polymers
DESCRIPTION
It is high time to realize responsibility towards Nature before the Nature reacts more adversely. Our need & greed has already disturbed the equilibrium, let's replenish! Adopt RECYCLING... be the change you wish to see in the world. A noble effort from PLUSS @ Technical Seminar on Engineering Plastic Waste Recycling organised by CIPET, AmritsarTRANSCRIPT

Engineering Polymers
MAJOR CLASSIFICATION*
* Scrap Generation wise
SOURCES OF SCRAP1.NYLONS: film, fiber, automotive parts, appliance housings, bearings, cable ties, gear wheels, cam, slides etc.
2.POLYESTERS (PET&PBT): food processor blades, vacuum cleaner parts, fans, hair dryer housings, coffee makers, switches, motor housings, fuse cases, key caps for computer keyboards, connectors, fiber optic buffer tubing etc.
3.POLYCARBONATES: computer parts, connectors, etc., food processors, refrigerator drawers, headlights, taillights, instrument panels, etc.

PROPERTIES OF IMPORTANCE
1. Good mechanical strength and rigidity.
Applications: Gear wheels for water meters, slides, cams, bearings etc.
2. High impact strength and toughness.
Applications: Appliance housings etc.
Nylon Scrap
But NYLON SCRAP lacks these!

Use LLD based Additives for:
Improving impact properties.
Imparting desired toughness.
Compatibilizing foreign particulates like mineral fillers and polymers like PE, PP etc.
E.g.: OPTIM® E-126
Use Elastomer based Additives for:
Impact properties at sub zero temperatures.
Super toughness properties.
Dispersion of both mineral fillers and glass fillers in the polymer matrix.
E.g.: OPTIM® E-131

www.pluss.co.in
1. PET scrap lack sufficient mechanical strength and impact properties.
Applications: head lamp reflectors and various structural automotive components etc.
2. PBT scrap lacks desired abrasion resistance and toughness.
Applications: electrical connectors, switches, key caps for computer keyboards, motor housings etc.
Polyester Scrap
So, PET/PBT scrap needs to be upgraded!

Almost All Polymer Waste is Recyclable.
The bottleneck is proper collection and segregation
and
Professional Recycling Organizations need to be set up!
