PET Formed Interior Felt

A door-panel frame can use 600–1,000 g/m² rigid PET felt. The acoustic liner can use 300–600 g/m² soft PET felt with an NRC of at least 0.65.

Where water protection or additional reinforcement is needed on the sheet-metal side, an 80–150 g/m² PET hot-rolled fabric combined with PE film can be used.

A headliner system can include a 600–1,000 g/m² rigid supporting layer and a 400–800 g/m² soft acoustic layer. Nonwoven or knitted fabric can be laminated to the visible surface during molding.

A sunroof reinforcement frame may also be integrated during forming. Completing several layers in one mold can reduce later spray-adhesive application, positioning, and secondary lamination.

A main-carpet system can use 300–600 g/m² PET needle-punched carpet or PA tufted material as the surface layer.

A 600–1,200 g/m² rigid PET felt with a thickness of 2–3 mm can provide the formed supporting structure. A 400–800 g/m² soft PET felt with a thickness of 10–20 mm can be used as the acoustic layer.

Trunk side panels may use 800–1,200 g/m² rigid felt laminated with fabric. Spare-wheel covers can use a multilayer rigid-felt structure of 1,000–1,800 g/m².

Parcel shelves may use 1,000–1,500 g/m² rigid felt. Tailgate interior panels can use 600–1,000 g/m² rigid felt together with an acoustic soft layer of about 300 g/m².

These system-specific combinations help control component weight, stiffness, and sound absorption without applying the same density to every interior part.

PET Formed Interior Felt does not contain glass fiber, reducing glass-fiber dust and skin irritation during handling and assembly.

Formaldehyde emission is no more than 15 μg/(m²·h). Total TVOC carbon is no more than 50 μgC/g, odor grade is no more than 3.5, fogging condensate is no more than 2 mg, and mold resistance is Grade 0.

The material complies with RoHS, REACH, ELV, and GB 30512 requirements. After 50 high- and low-temperature cycles between -40°C and +120°C, the product does not crack or separate.

After 1,000 hours at 50°C and 95% RH, strength retention can reach more than 85%.

Jiangsu Haokai can support material selection, mold development, sample validation, and volume production according to the vehicle interior system. Products receive 100% inspection before packing, and third-party inspection is accepted.
