Torlon®Quadrant Pai Torlon 4203 Sheet polyamide-imide offers excellent compressive strength and the highest elongation of the Torlon® grades. It also provides electrical insulation and exceptional impact strength. This Torlon grade is commonly used for IC Test Sockets & Handlers, as well as, electrical connectors and insulators due to its high dielectric strength. Its ability to carry high loads over a broad temperature range makes it good for structural components such as linkages and seal rings. Torlon®4203 is also an excellent choice for wear applications involving impact loading and abrasive wear.
The parts processed by Duratron®T4203 PAI have a high level of tensile strength and compression resistance to ensure that the parts have good mechanical load capacity. In addition, Torlon material has higher toughness and rigidity. Mechanical rigidity, low thermal expansion coefficient and thermal stability help to obtain dimensionally stable finished parts. It is possible to modify PAI plastics, usually adding glass fiber or carbon fiber to improve strength and stiffness, or adding PTFE or other lubricants to reduce friction and improve wear resistance, including dry running conditions. However, the high hygroscopicity of Torlon material may cause dimensional changes and is sensitive to exposure to saturated steam. Torlon PAI material has an excellent balance of mechanical properties, electrical properties, chemical resistance, thermal properties and friction properties, and has good performance in extreme high temperature conditions.
Features of Torlon Pai Sheet Rod & Tubes:
Torlon 4203 Pai Sheet Application
Semiconductor industry: test sockets, electronic connectors and insulators
Aerospace: Fasteners, insulators and other components
Oil and gas: natural gas compressor components, pump components and labyrinth seals
General industry: bearings and wear-resistant parts, as well as parts requiring high strength and high hardness
DURATRON (TORLON) 4203 PAI offers the best toughness and impact strength of all DURATRON (TORLON) PAI grades. Because of its intrinsic high temperature resistance, high dimensional stability and good machinability, this extruded DURATRON (TORLON) PAI grade is very popular for precision parts in high-tech equipment. In addition, its good electrical insulating ability provides numerous possibilities in the field of electrical components.
Delivery Programme: rod 2.38 - 50.80 mm, plate 6.35 - 25.40 mm
This compression moulded material is similar in composition to DURATRON (TORLON) 4203 PAI, and is selected when larger shapes are required.
Delivery Programme: rod 50.80 - 368.30 mm, tube 42.86 - 882.65 mm
The addition of PTFE and graphite provides higher wear resistance and lower coefficient of friction compared to the unfilled grade as well as little or no stick-slip in use. This extruded grade excels in severe wear applications such as non-lubricated bearings, seals, bearings cages and reciprocating compressor parts.
Delivery Programme: rod 2.38 - 50.80 mm, plate 6.35 - 25.40 mm
This compression moulded material is similar in composition to DURATRON (TORLON) 4301 PAI, and is selected when larger shapes are required.
Delivery Programme: rod 50.80 - 368.30 mm, plate 9.53 - 50.80 mm, tube 42.86 - 882.65 mm
This compression moulded, 30 % glass fibre reinforced grade offers higher stiffness, mechanical strength and creep resistance than DURATRON (TORLON) 4203 PAI and DURATRON (TORLON) 4503 PAI. It is well suited for structural applications supporting static loads for long periods of time at high temperatures. The suitability of DURATRON (TORLON) 5530 PAI for sliding parts, however, is to be carefully examined since the glass fibres tend to abrade the mating surface.

With the continuous decline in product prices in recent years, even the high-end products such as international brands such as Philips and Osram, the price will not be higher than the domestic first-line brand products. LED lighting products have become more intimate and gradually accepted by consumers.
At present, LED bulbs are mainly 3W, 4W, 5W, 7W, and 9W, of which 3W and 5W are the largest. According to the research data of LED Light Bulb Terminals in major cities across the country, the average selling price of key brands 3W, 5W and 7W LED bulbs was 26.17 yuan and 38.35 yuan respectively. And 54.75 yuan.
Due to space reasons, this survey only selected ten representative companies for analysis. Among the ten companies, the average selling price of LED bulbs is Osram, the average price of 3W is 40.43 yuan, the average price of 5W is 57.43 yuan, and the average price of 7W is 92.86 yuan. The lowest average selling price of the terminal is Mulinsen, 3W. The average selling prices of 5W and 7W bulbs are 13.75 yuan, 20.75 yuan and 27.50 yuan respectively.
In August 2013, the average selling prices of the 0.6m, 0.9m and 1.2m product terminals of 10 representative brand LED fluorescent tubes were 61.73 yuan, 75.87 yuan and 99.90 yuan respectively.
Among them, the price of each type of LED fluorescent tube of Osram is the highest, and the average selling price of 0.6m, 0.9m and 1.2m are 135 yuan, 142 yuan and 169.33 yuan respectively. The average selling price of Mulinsen's 0.6m, 0.9m and 1.2m fluorescent tubes was the lowest, at 26.5 yuan, 37.75 yuan and 45.75 yuan respectively.
According to GLII research, LED downlights on the market are mainly 2.5 inches 3W, 5W, 4 inches 5W, 7W, 9W. In August 2013, the average selling price of the five types of LED downlights of 10 representative enterprises was 59.07 yuan, 76.59 yuan, 88.81 yuan, 115.19 yuan and 159.95 yuan respectively.
The average selling price of the five mainstream models of Philips LED downlights is 81.63 yuan, 123.38 yuan, 163.18 yuan, 186.37 yuan and 230.50 yuan, which is much higher than the prices of other brands of downlights.
