Lexan* Extrusion Resin
Resins for Extrusion Blow Molding
Specially developed UV-stable Lexan Resin extrusion grades can be readily extruded on conventional equipment. The range includes both linear and branched polymers for profile and solid, multi- and twin-wall sheet extrusion, including glass clear UV cap-layer materials. For typical applications many critical standards can be met for outdoor weatherability, while providing enhanced productivity.
Lexan* Resin 103 数据
UL rated HB as of 10/97. 200 series recommended when V-2 rating required. Nonhalogenated. 7.0 MFR, for thicker sections without sinks. UV stabilized for outdoor and lighting.

1、 Typical values only. Variations within normal tolerances are possible for various colors. All values are measured after at least 48 hours storage at 23℃/50% relative humidity. All properties, except the melt volume and melt flow rates, are measured on injection molded samples. All samples tested under ISO test standards are prepared according to ISO 294.
2、Only typical data for selection purposes. Not to be used for part or tool design.
3、This rating is not intended to reflect hazards presented by this or any other material under actual fire conditions.
4、Internal measurements according to UL standards.
5、Measurements made from laboratory test coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
