Battery Thermal Management System Compressive Pad Close Cell Foam Tensile Elongatio 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.
Expanded polypropylene foam (EPP foam) and expanded polyethene (EPE foam), is produced by applying heat, pressure and a blowing agent in an autoclave. The material is then made into small plastic beads. These beads are then injected into molds using steam heat and pressure to create virtually any shape.

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.
