APPLICATION AREA
Polycarbonates are plastics widely used in modern industry having good temperature and impact resistance. This plastic is particularly good to work with more conventional definition techniques (injection molding, extrusion into tubes or cylinders and thermoforming). It is also used when optical transparency is needed, having more than 80% transmission up to the 1560-nm range (short wave infrared range). It has moderated chemical resistance properties, being chemically resistant to diluted acids and alcohols. It is poorly resistant against ketones, halogens, and concentrated acids. The major disadvantage associated with polycarbonates is the low glass transition temperature (Tg> 40°C), but it is still largely used as low-cost material in microfluidic systems and also as a sacrificial layer.HOW TO BUY FROM US
5. Delivery documentation The following documents are provided with each delivery: · Bill of Lading, CMR Waybill or other relevant transport document · Certificate of Analysis or Conformity (if required) · HSSE-related documentation in line with regulations · Customs documentation in line with regulations (if required)1. Security Safety is our top priority. In addition to providing customers with information about the safe and environmentally friendly use of our products, we are also committed to ensuring that the safety risks of employees and contractors are reduced to a reasonable and feasible minimum. Therefore, we require the customer to ensure that the appropriate unloading and storage safety standards are met before our delivery (please refer to the HSSE appendix in the general terms and conditions of sales below). Our HSSE experts can provide guidance on these standards.2. Delivery method Customers can order and deliver products from chemwin, or they can receive products from our manufacturing plant. The available modes of transport include truck, rail or multimodal transport (separate conditions apply). In the case of customer requirements, we can specify the requirements of barges or tankers and apply special safety/review standards and requirements.3. Minimum order quantity If you purchase products from our website, the minimum order quantity is 30 tons.4.Payment The standard payment method is direct deduction within 30 days from the invoice.Chemwin can provide a wide range of bulk hydrocarbons and chemical solvents for industrial customers. Before that, please read the following basic information about doing business with us: Polycarbonate (PC) is a colorless, transparent, glassy amorphous polymer with excellent optical properties. PC high molecular resin has high toughness, cantilever beam notched impact strength is 600~900J/m. The unfilled grade has a heat distortion temperature of about 130 °C, which can be increased by 10 °C after it is reinforced with glass fiber. The flexural modulus of PC can reach more than 2400 MPa, so it can be processed into a large rigid product. Below 100 ° C, the creep rate under load is very low. PC is poor in hydrolysis resistance and cannot be used to repeatedly process articles subjected to high pressure steam.
