Engineering Polymers
MAJOR CLASSIFICATION*
* Scrap Generation wise
SOURCES OF SCRAP
1.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
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!

PLUSS®

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!

PLUSS®
www.pluss.co.in
Using Additives such as
OPTIPET™ 213M
Improves impact properties.
Impart desired toughness.
Compatibilize foreign particulates like
mineral fillers and polymers like PE or PP
etc.
 Compatibilize PET/PBT scrap.

Polycarbonates

PLUSS®
www.pluss.co.in
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!

PLUSS®
www.pluss.co.in
Use additives such as OPTIM®
GE-344
Improves impact properties.
Impart desired toughness.
Compatibilize foreign particulates like
mineral fillers and polymers like PE or PP
etc.
 Compatibilize PET/PBT scrap.

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

PLUSS®
in Recycling
 CONSULTANCY: Provides
solutions for recycling of
engineering polymers:
Nylons, PET/PBT, PC
 ADDITIVES: Provides
speciality polymers to
improve the properties of
polymer scrap.
 VALUE ADDITION:
Identifying applications and
uses for your polymer waste

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