Lexan* Structural Foam Resin
Strength at Low Weight with Foam
Lexan Resin structural foam grades may be an ideal choice for structural components, as well as an excellent alternative to metal. For the production of large parts such as outdoor distribution cabinets, Lexan Resin foams can provide important weight savings through an inherently high stiffness-to-weight ratio.

Lexan* Resin FL903 英文数据物性表
Various weight reductions at 0.250" (6.35 mm). High heat/creep resistance, excellent impact, flexural strength/rigidity. UV-stabilized.

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.
