LDPE for Injection Molding
LDPE for Injection Molding in Gujarat
What is LDPE?
LDPE (Low-Density Polyethylene) is a thermoplastic polymer made from the monomer ethylene. Known for its flexibility, chemical resistance, toughness, and transparency, LDPE is widely used in injection molding to manufacture both industrial and consumer plastic products.
In Gujarat—a hub for petrochemical and polymer manufacturing—LDPE is extensively supplied to moulding units, plastic component manufacturers, and packaging industries.
Where LDPE is Used in Injection Molding:
-
Household items – lids, containers, food storage items
-
Agricultural equipment – sprayer parts, covers, fittings
-
Medical supplies – squeeze bottles, caps, dropper bulbs
-
Electrical insulators – low-voltage protective covers
-
Packaging industry – caps, plugs, closures
-
Consumer goods – toys, flexible components, handles
-
Automotive industry – gaskets, clips, minor covers
-
Industrial applications – chemical-resistant parts, seals
Key Uses :
-
Making lightweight, durable parts
-
Creating flexible yet strong components
-
Ensuring resistance to acids, bases, and alcohols
-
Supporting cost-effective, high-speed production
-
Manufacturing recyclable and reusable plastic products
Importance :
-
Excellent moldability – flows easily into complex moulds
-
Good impact strength – withstands drops and flexing
-
Low moisture absorption – suitable for sanitary and food-safe items
-
UV-resistant grades – for outdoor applications
-
Low processing temperature – saves energy costs
-
Cost-efficient – lower price compared to PP or HDPE in many cases
