Polyolefin Foam Insulation Expanded Crosslinked Ixpp/Xpp Foam Sheet

Product Description

IRRADIATION CROSS LINKED POLYPROPYLENE FOAM

Product Description

Irradiated crosslinked polypropylene foam-IXPP is mainly made of polypropylene, foaming agent and other additives through melt mixing and extrusion molding, then undergoes green and healthy ion radiation
crosslinking through irradiation processing technology.
It is formed through continuous high-temperature foaming and possesses an independent closed-cell structure.
IXPP foam has good thermal stability, cushioning and rebound properties, and can be widely used in industries  such as automotive interior, aerospace, marine machinery, sports and leisure.

Application:

 

♦ IXPP foam has good thermal weldability, thermal processing performance and dimensional stability at high temperature (130°C), and can be used for steaming sand of car roofs, steering wheels, luggage compartment linings and air conditioners Damping panels, side guards, energy-absorbing protection pads for inner door panels, buffer pads, headrests, etc.
♦IXPP is suitable for high-temperature applications, such as car roofs, air conditioner panels, and instrument insulation. It's commonly used as lining and damping material in high-end cars.
♦IXPP can be used as a thermal insulation material for 90~120°C heat carrier cycle batteries and as an engine room heat insulation material.

• Automotive Industry: Used for interior components such as door panels, headliners, dashboards, and seat cushioning. IXPP foam provides sound insulation, heat resistance, and lightweight strength, which improves fuel efficiency.

• Packaging: Offers excellent shock absorption and resilience, making it suitable for protective packaging of electronics, precision instruments, and fragile goods.

• Construction: Acts as thermal and acoustic insulation in flooring, roofing, and wall systems. It is resistant to moisture and chemicals, enhancing long-term durability.

• Consumer Products: Found in sports equipment, household items, and protective cases where cushioning, flexibility, and safety are important.

• Electronics: Serves as insulation and shock-absorbing layers for sensitive components, reducing damage during transport or use.

FAQ

Q: Do you manufacture your own foam?

A: Yes, we do manufacture the foam using our own presses and molds. We have various sizes molds.

Q: Why your price labeled so cheap?

A: We manufacture the foam buns our self, and export directly, no extra fees added.

Q: What is your lead time?

A: Ninety percent of all our orders can be loaded in 15 days.

Q: How much can you fit on a 40 HQ container?

A: Approximately 205 buns of 4" x 48" x 96"

Q: What is your minimum order?

A: We do not have a minimum order. However, small qty will be waste for the shipping costs.

Q:What are acceptable forms of payment?

A: We accept wire transfers, TT payment, Paypal, Western Union, LC etc.

Q: What densities are available?

A: We stock 1.5lb to 15lb densities.

Q: What colors are available?

A: Charcoal; Light Charcoal; Grey; Mint Green; Blue; White; Yellow; Red; Lavender; Lime Green; and Natural.

Q:Does your material come with skins?

A: Generally no, although some materials are available with skins upon request.

Q: What can be used to cut your foam?

A: Most tools that can be used to cut wood can also be used to cut our foam. These include table saws, band-saws, table routing, water-jet, etc.

Q: What is the working temperature of the foam?

A:Maximum continuous operating temperature of our foam is between -110°F to 180°F (-79°C to 82°C)

Q: What is the shelf life of the foam?

A: Crosslinked polyethylene foam does not have a shelf life.

Q: Does the foam float?

A: Yes, it does; XLPE is a water resistant foam.

Q: What are the differences between EVA and XLPE?

A: EVA is soft. Our XLPE and EVA foam products are similar materials and are difficult to distinguish. 

The primary differences are that EVA is softer, more resilient, and has stronger recovery after compression. Whereas polyethylene foams are firmer and more resistant to heat. 

Both of them provide excellent protection and shock absorption for packaging applications.
