Recycling of engineering polymers
May 25, 2015
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.

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.

Nylons
PLUSS®
www.pluss.co.in PLUSS®
www.pluss.co.in
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

Polyesters (PET & PBT)
PLUSS®

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!

Using Additives such as OPTIPET™ 213MImproves impact properties.
Impart desired toughness.
Compatibilize foreign particulates like mineral fillers and polymers like PE or PP etc.
Compatibilize PET/PBT scrap.

PROPERTIES OF IMPORTANCE
1. Good dimensional stability and superior mechanical strength.
Applications: instrument panels, computer parts etc.
2. High heat and impact resistance.
Applications: headlights, taillights, refrigerator drawer etc.
Polycarbonate Scrap
But Polycarbonate scrap lacks these!

Factors Affecting Polymer Recycling
Identification and Segregation of Polymer waste
Shear Rate in the Compounding Machine used
Temperature
Composition of the mix
Residence Time
Additives Package
Equipments & Conditions for Subsequent Processing

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