The document discusses the differences between low-density polyethylene (LDPE) and high-density polyethylene (HDPE), highlighting their chemical properties, flexibility, durability, and best applications. LDPE is suitable for components requiring stretch and flexibility, while HDPE is preferred for its strength and rigidity. Additionally, it mentions Essentra Components' commitment to sustainability by incorporating recycled materials and improving manufacturing practices.

1. LDPE OR HDPE?
HOW TO CHOOSE THE RIGHT
THERMOPLASTIC FOR YOUR COMPONENT

2. These two types of
polyethylene have
different chemical
structures.
This affects

12. BEST APPLICATIONS
FOR LDPE VS HDPE

13. LDPE
Stretch Fit
Flexibility allows a cap to stretch over
screws and pipes ensuring a close fit
for masking
Push Fit
The rigidity of a HDPE cap

14. APPLICATIONS BY
END-PRODUCT TYPE

15. • Use LPDE when
flexibility is needed.
• Use HDPE when
strength is needed.
PROTECTION PARTS

16. HARDWARE PARTS
•
Use LDPE for tube
inserts and glides,
offering secure
fitting and covering
sharp edges.

17. FASTENERS
• Not appropriate to use as
fastener. Use nylon instead
as it is more durable and
stronger for use as washers,
screws
and nuts.

improve their sustainability score

21. Essentra Components
has invested into new
injection moulding machinery
that mixes virgin plastics resins
with post-consumer resin

22. From spring 2021, nearly all
LDPE products produced at the UK
facility have been manufactured
using at least 40% recycled plastics.
