An Analysis of Export Duty-Free Pallets: Exploring the Uses of Duty-Free Pallets

Rigid PVC products include pipes and rods, boards, welding rods, centrifugal pumps, ventilators, wheel oil pipes, valves for acid and alkali pumps, and containers, etc.

Our products include storage tanks, thin plates, films, wire insulation, window seals, and acid and alkali-resistant hoses made of soft polyvinyl chloride.

Polyethylene (PE)

Performance:

Available in three types: high-pressure, medium-pressure, and low-pressure polyethylene. High-pressure polyethylene is flexible and pliable; low-pressure polyethylene is hard and has excellent cold resistance, remaining soft at -70℃. It boasts high chemical stability, withstanding acids, alkalis, and organic solvents. It exhibits remarkable electrical properties and good radiation resistance. Applied to metal surfaces using flame spraying or electrostatic spraying methods, it achieves both lubrication reduction and corrosion prevention. Its drawback lies in its low mechanical strength and low thermal deformation temperature, making it unsuitable for high-load applications.

Purpose of the Exempt Inspection Pallets:

Corrosion-resistant linings for chemical equipment and storage tanks, chemical corrosion-resistant pipes, valves, sleeves, and roller frames, as substitutes for copper and stainless steel. Insulation for high-frequency underwater cables or general cables. Magnetic rod antenna brackets for transistor radios.

Styrene (PS)

Performance:

It possesses good mechanical strength, chemical stability, and electrical properties, excellent transparency, and fine coloring. It is also easy to shape. Its main characteristic is its near-complete resistance to water, but it has a lower heat resistance and is somewhat brittle. Additionally, its products are prone to cracking due to internal stress, and can only be used under low loads and temperatures not exceeding 60-75°C.

Usage:

A variety of instrument shells, frames, gauge indicators, lamp shades, automotive lamp shades, chemical storage acid tanks, acid transport tanks (especially hydrofluoric acid), chemical instrument parts, telecommunications components, and optical instrument parts and lenses, due to their high transparency.

High-Impact Polystyrene (HIPS)

Performance:

Compared to polystyrene, it boasts higher toughness and impact resistance, with the rest of its properties largely similar and excellent molding processes.

Purpose:

A variety of instruments, transistor radio casings, coil cores, textile yarn tubes, TV structural parts, agricultural vehicle waterboard accessories, and small plastic pipes and plates.

Styrene Modified Acrylic Glass

Uninspected Pallet Performance:

The product offers good transparency, high mechanical strength, and certain heat, cold, and weather resistance, as well as corrosion resistance and good insulation. The dimensions of the products are stable and easy to form. Its drawbacks include being brittle, easily soluble in organic solvents, and not having enough surface hardness for transparency, making it prone to scratching. Overall, it outperforms general plastics like polystyrene.

Purpose:

Parts used to produce items with specific transparency and strength, such as oil gauges, oil cups, optical lenses, lenses, equipment labels, transparent pipes, automotive headlights, and scale disks for transistor radios, as well as electrical insulation components.

Styrene Acrylonitrile Copolymer (AS or SAN)

Performance:

With higher impact strength than polystyrene and excellent heat resistance, oil resistance, and chemical corrosion resistance, it can withstand certain hydrocarbons that cause stress cracking in polystyrene. Additionally, its elastic modulus is one of the higher ones among existing thermoplastic resins.

Uninspected Pallet Usage:

Widely used in the production of industrial products that are oil-resistant, heat-resistant, and chemically resistant, as well as for instrument panels, instrument frames, casings, battery boxes, junction boxes, and a variety of switches and switches according to specifications.
