Proper Use of SUMIKASUPER LCP
The contents of this document have been compiled based on current documents, information, and data and may be revised when new information is available.
(1) HandlingThe following items refer to essential points when handling SUMIKASUPER LCP. Ensure that SUMIKASUPER LCP is handled safely. Carefully read the Material Safety Data Sheet regarding the handling of SUMIKASUPER LCP before use. Examine the safety of any additives for use with SUMIKASUPER LCP.
[1] Safety and Health Ensure that any gases emitted from drying or melting SUMIKASUPER LCP do not come in contact with the eyes or skin or are inhaled. In addition, be careful not to touch the resin while it is still hot. Local ventilation equipment must be installed and proper protective gear (such as protective goggles and protective gloves) must be worn while drying or melting this product.
[2] FlammabilitySUMIKASUPER LCP is a ame-resistant material (classied as UL94 V-0), however, it should be handled and stored in places well away from sources of heat and ame. If the material catches re, toxic gases may be released. Use water, foam, or chemical re extinguishers to extinguish any ames.
[3] Disposal SUMIKASUPER LCP may be disposed by burial or incineration. Burial of the material should be conducted by certied industrial waste processors or by the local municipal authorities in accordance with the "Waste Management and Public Cleansing Law". Incineration should be conducted using a furnace which complies with the laws and regulations of the Air Pollution Control Law. Toxic gases may be released when this product is incinerated.
[4] Storage Store SUMIKASUPER LCP at room temperature away from direct sunlight, water, and humidity.
(2) Applicable StandardsSUMIKASUPER LCP comes in a variety of grades which comply with standards specied by the American Underwriters Laboratories Inc., i.e. UL94 and UL746, and by the Electrical Appliance and Material Control Law, i.e. ball pressure temperature. Refer to this booklet or contact Sumitomo Chemical for further details. Contact Sumitomo Chemical for information regarding the use of this material in other special applications.
(3) Security Trade ControlThe products of SUMIKASUPER E5000 series, E4000 series, E6000 series, SZ4000 series and SZ6000 series are on the control list of the Foreign Exchange and Foreign Trade Control Act of Japan.The SUMIKASUPER E6000HF series and SZ6000HF series are not on the control list but implemented in catch-all control.

As indicated by their name, one property of liquid crystalline polymers is that they become liquid crystalline state when they enter a molten state. This special phenomenon, unique to liquid crystal polymers, can be observed under a polarizing microscope: as the temperature of a polymer increases and it begins to melt, its light transmittance also increases signifi-cantly.
SUMIKASUPER LCP is a thermotropic liquid crystalline polyester that possesses the highest heat resistance among all engineering plastics. Its basic chemical composition is shown in the diagram below. Thermotropic liquid crystalline polyester is one of the most common types of liquid crystalline polymer.
