| Product Description |
|
Petra 330 FR BK-112 is a 30% glass reinforced, flame retardant
PET, pigmented black injection molding compound rated UL94 V-0
in a 1/64 inch thickness. The product is designed for injection
molding of thin and complex parts such as electrical bobbins.
Due to its high crystallization rate the processability of the
product in the injection molding process is very good.
It exhibits excellent balance of properties including strength,
stiffness, HDT, dimensional resistance and electrical properties.

Material Handling
Max. Water content: 0.01%
To ensure optimum part performance, this product must be dried prior to molding and maintained at a moisture level of less than 0.02%. Dehumidifying or desiccant dryers operating at 120 °C and 2 to 4 hours drying time is recommended. Further information concerning safe handling procedures can be obtained from the Material Safety Data Sheet. Alternatively, please contact your BASF representative.
Typical Profile
Melt Temperature 280-300 °C (536-572 °F)
Mold Temperature 100-110 °C (212-230 °F)
Injection and Packing Pressure 35-125 bar (500-1500 psi)
Mold Temperatures
This product can be processed over mold temperatures of 80-120 °C (176-248 °F); however, for optimizing surface appearance, dimensional stability and part performance, mold surface temperatures of 100-110 °C (212-230 °F) are preferred.
Pressures
Injection pressure controls the filling of the part and should be applied for 90% of ram travel. Packing pressure affects the final part and can be used effectively in controlling sink marks and shrinkage. It should be applied and maintained until the gate area is completely frozen off. Back pressure can be utilized to provide uniform melt consistency and reduce trapped air and gas. Minimal back pressure should be utilized to prevent glass breakage. recommended to minimize glass fiber breakage.
Fill Rate
Fast fill rates are recommended to ensure uniform melt delivery to the cavity and prevent premature freezing. Surface appearance is directly affected by injection rate.
