| (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°C/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. |
