Solution
TPU/ABS composite plate is one new kind of environment friendly material used for car gauge panel and inner decoration. It adopts multi manifold process to make TPU coat on ABS instead of glue coating so that the finished product does not release formaldehyde or inner air pollution. Plate thickness from 1mm to 8mm, width from 1200mm to 2000mm.
TPO composite leather roll(coating roll) has the advantages of environment friendly and abrasion and heat resistance. It has been used widely in the field of car inner decoration, instrument board skin, inner decoration skin, in-car flooring, car rear tank flooring, foot pad material. Its regular thickness is 0.2-3mm with width 1000-2000mm

An EVA POE TPO soundproof sheet extrusion line is a specialized production system that manufactures automotive sound insulation pads (also known as vibration damping pads) from EVA (ethylene vinyl acetate), POE (polyolefin elastomer), TPO (thermoplastic polyolefin), PVC, and high-filling inorganic materials. These soundproof sheets are high-density panels applied directly to metal body parts to absorb vibrations and block noise transmission. JWELL Machinery’s extrusion lines produce soundproof sheets with thicknesses from 0.6 mm to 8 mm and widths from 1,000 mm to 3,000 mm, serving the automotive interior and NVH (noise, vibration, and harshness) control industry.
Automotive sound deadening sheets are produced using EVA (ethylene vinyl acetate), POE (polyolefin elastomer), TPO (thermoplastic polyolefin), and PVC (polyvinyl chloride) as base polymers, compounded with high-filling inorganic materials such as barium sulfate, calcium carbonate, or other mineral fillers. The high inorganic filler content increases the sheet density, which is essential for effective vibration damping and noise absorption. JWELL’s soundproof sheet extrusion lines are engineered to handle these heavily filled compounds, ensuring uniform dispersion and consistent sheet quality.
EVA and TPO soundproof sheets are installed throughout the vehicle body at key noise and vibration source points. Primary application locations include the hood (engine noise isolation), doors (road and wind noise reduction), luggage compartment (trunk noise control), roof panel (overhead noise damping and thermal insulation), and fender/wheel arch areas (tire and road noise absorption). These sound deadening pads serve a dual purpose: they reduce NVH levels and contribute to structural reinforcement and thermal insulation of the vehicle body.
EVA (ethylene vinyl acetate) offers excellent flexibility, closed-cell foam properties, and good vibration absorption, making it the most widely used sound deadening material in automotive applications. POE (polyolefin elastomer) provides superior elasticity, weather resistance, and lower density compared to EVA, making it suitable for lightweight noise control solutions. TPO (thermoplastic polyolefin) combines the processing advantages of polypropylene with the flexibility of elastomers, offering recyclability and cost-effectiveness. Each material can be processed on JWELL extrusion lines, allowing manufacturers to produce soundproof sheets that meet specific automotive OEM requirements.
JWELL EVA POE TPO soundproof sheet extrusion lines produce sheets with thicknesses ranging from 0.6 mm to 8 mm and widths from 1,000 mm to 3,000 mm. The line configuration can be customized to match specific automotive part dimensions. Thinner sheets (0.6–3 mm) are typically used for door panels and interior trim applications, while thicker sheets (3–8 mm) are applied to hood, floor pan, and firewall areas requiring higher mass loading for effective noise reduction.
High-filling inorganic materials (such as barium sulfate, calcium carbonate, or talc) are added to the polymer matrix at ratios of 50–70% by weight to increase the sheet’s density and mass, which directly improves vibration damping performance. However, high filler content presents extrusion challenges including increased melt viscosity, accelerated screw and barrel wear, and potential filler dispersion issues. JWELL’s soundproof sheet extrusion lines address these challenges with wear-resistant screw and barrel designs, optimized L/D ratios, and specialized mixing sections that ensure homogeneous filler distribution throughout the sheet.
EVA and TPO soundproof sheet production typically uses a single-screw extruder with a dedicated mixing section, although twin-screw extruders may be employed for formulations requiring intensive compounding of high-filling inorganic materials. The screw design features a large L/D (length-to-diameter) ratio for improved melting and mixing of heavily filled compounds. JWELL manufactures its own screws, barrels, dies, calender rolls, and screen changers in-house, ensuring precise control over the critical wear components required for abrasive, high-filler-content sound deadening materials.
Yes, JWELL’s soundproof sheet extrusion lines can be configured to process both EVA/POE/TPO and PVC materials, though the extruder type and screw design differ. EVA, POE, and TPO are processed on single-screw extruders, while PVC requires a conical twin-screw extruder due to PVC’s thermal sensitivity and shear degradation characteristics. When manufacturing multiple material types, the die, calender, and downstream equipment can be shared, but the extruder unit may need to be exchanged or reconfigured. JWELL’s engineering team can design a flexible production layout for manufacturers producing both material categories.
While both lines produce polymer sheets, they serve different functions and require different equipment configurations. Soundproof sheet extrusion lines produce dense, heavy, high-filler-content sheets (0.6–8 mm) optimized for vibration damping and noise absorption in automotive applications. Waterproof membrane extrusion lines (such as TPO, PVC, or HDPE geomembrane lines) produce thinner, flexible sheets designed for water impermeability in roofing, tunneling, and civil engineering applications. JWELL offers both types of production lines, and some TPO-based products can serve dual waterproof and soundproof functions depending on the formulation and installation requirements.
