Battery Thermal Management System Compressive Pad Close Cell Foam
Acoustic Insulation Expanded Polystyrene Foam
EPP foam is an excellent material for NEV battery insulation,
thanks to its high thermal resistance. It can effectively dissipate
heat generated during battery operation, helping to maintain
optimal operating temperatures and preventing thermal runaway. EPP
foam is also an effective insulator, providing excellent thermal
insulation properties that can help reduce energy consumption and
improve battery performance.
EPP foam is also an ideal material for NEV battery protection
against impact. It can absorb and disperse impact energy, reducing
the risk of battery damage or rupture in the event of a collision.
Its ability to regain its original shape after deformation ensures
the battery's structural integrity remains intact, thereby
safeguarding the vehicle's occupants and critical electrical
components.
NEV manufacturers aim to increase driving range and optimize energy
efficiency. EPP foam's lightweight construction contributes to
achieving these goals by reducing the overall weight of the battery
module. This helps to improve the vehicle's performance and extend
the battery's range without compromising on safety or durability.
Vibrations during vehicle operation can impact battery performance
and lifespan. EPP foam exhibits excellent vibration damping
properties, minimizing the effects of external vibrations on the
battery pack. This ensures stable operation, reduces the risk of
internal damage, and extends the battery's service life.
EPP foam is also an environmentally friendly material. It is 100%
recyclable and can be easily processed into various shapes and
sizes, minimizing waste generation during production. Choosing EPP
foam for NEV batteries aligns with the sustainable ethos of the EV
industry, contributing to a greener future.
This is a light weight and durable foam that can be used to create
various parts for radio control planes and for other hobbies. The
foam is cut with a knife which gives a slight deviation in
thickness. This also means there is no skin left over from a hot
wire cut.

EPP is widely utilised by automotive manufacturers because of its
performance benefits for energy management, lightweight, enhanced
functionality, durability and recyclability. Applications include
seating, bumpers, stowage systems, door panels, pillars, floor
levellers, parcel shelves, headrests, tool kits, sun visors and
myriad filler parts.
Reusable industrial packaging, known as dunnage, is frequently made
from EPP due to its durability and its inherent ability to absorb
energy in transit. EPP is used increasingly in furniture, toys such
as model aircraft and other consumer products due to its
versatility as a structural material and its lightweight, as well
as other performance characteristics. appro colour range
EPP is approved for use in conjunction with food products. Its
thermal insulation properties and structural strength make it
appropriate for containers such as food delivery containers and
beverage coolers and the like. EPP does not support microbial
growth and can be made sterile with steam cleaning.
