SUNGNAM ELECTRICS, founded in 1976, has continuously accumulated technology to develop high quality materials for the electrolytic capacitor industry. Sungnam has foreseen the needs of its market and has faithfully met various demands of its customers. Sungnam has introduced revolutionary products for the 21st century such as PVC heat shrinkable tube, GS (Greenstar) tube and SD Rubber Bungs. All these materials are environment-friendly with highest product characteristics. This only confirms the commitment and technical expertise of our principals. This page is particularly dedicated to PVC Sleeves for your benefit.
Some of the characteristics of the PVC heat shrinkable tube are mentioned below:
Shrinks to its original state after it is heated.
Excellent heat resistance temperature, which ranges from -55 ~ 105 deg. C.
The continuous monitoring of their automated production process ensures that all parameters (heat resistance, shrink ratio, printing, tolerance) of the PVC tube meet customers' requirements.
Apart from the above, Sungnam:
is an ISO 9001 Company confirming highest product design and customer oriented quality.
is an affiliate of Samyoung Capacitor Co. This association benefits Sungnam in
developing high quality Sleeves and gauging the future needs of a changing
marketplace.
perpetually tries to improve quality with continuous R&D.
