Within each region customers can count on our innovative research, development, and support facilities. Products made from polycarbonate can contain the pre Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. Polycarbonate remains one of the fastest growing engineering plastics as new applications are defined; global demand for PC exceeds 1.5 million tons. Demands include high service temperature, spike temperature resistance, ductility and toughness in thin sections, and flammability. What Services Do You Offer Besides Fabrication and Machining?

n���ץ��о. DSM Engineering Plastics operates in all major markets of the world including the Americas, Asia, and Europe. 0000001426 00000 n
Creep resistance is also excellent across a broad temperature range. 0000000536 00000 n
PC has been part of this history and continues to bring innovation, which allows automakers to produce lighter, stronger, and more durable components. Our in-house resources are backed by a corporate research and development center that is utilized in creating new solutions for customer needs. All Blends are produced using a compounding step to blend the polymers. All of this must be delivered consistently throughout the world, with co-ordinated engineering, market development, and technical service. Polycarbonate, an amorphous polymer, offers a unique combination of toughness with exceptional impact strength.

All rights reserved, Exceptional clarity and light transmission. Polycarbonate is most commonly formed with the reaction of bis-phenol A (produced through the condensation of phenol with acetone under acidic conditions) with carbonyl chloride in an interfacial process. ����^�+����sM���U���;Hv5/�`KZ�2��q�Q�K[9�3� The use of Engineering Plastics in automotive applications is nearing its fiftieth anniversary.
Polycarbonate Properties and Material Options. Typical blends include rubber modified PC, improving impact properties, PC/PBT blends, which allow toughness to be retained at lower temperatures and having improved fuel and weather resistance.
They are easily worked, molded, and thermoformed. POLYCARBONATE (PC) Physical and mechanical properties: Polycarbonate is a polymer which, when uncrystallized, has excellent transparency. TUFFAK® Polycarbonate– Tough and half the weight of plate glass, allows structural applications to require less support. Note that these ratings are generalised. Creep resistance is also excellent across a broad temperature range. It is
stream The material is amorphous (thereby displaying excellent mechanical properties and high dimensional stability), is thermally resistant up to 135°C and rated as slow burning. Aromatic Hydrocarbons *
Notched Impact Strength 60 - 80 Kj/m²
The material is amorphous (thereby displaying excellent mechanical properties and high dimensional stability), is thermally resistant up to 135°C and rated as slow burning. The industrial grades of PC have molecular weights on the order of 20,000 to 50,000g.mol-1.
This compounding technology is very important for creating the optimal morphology and interaction between the two phases. The largest UK application for PC is in the optical media market (i.e. Polycarbonate sheet thermoforms well, is easy to paint, and bonds well using solvent cements or adhesives. Typical examples of applications of technology are within: Automotive
PC/ABS blends exhibit high melt flow, very high toughness at low temperatures and improved stresscrack resistance compared to PC. This is followed by an assortment of sheeting and glazing applications.
Because of these properties, polycarbonates find many applications. <]>>

Although Polycarbonate is known for its high impact resistance, it is very susceptible to scratching. Miniaturisation fast product cycles make the E&E market one of the most demanding for Engineering Plastics. In applications such as baby bottles, plastic materials due to the inherent safety (unbreakable) and the design freedom they offer are increasingly replacing glass. D.W. Van Krevelen, ... K.
