A new grade of Borstar PE for injection moulding provides an alternative to extrusion materials for pipe fitting manufacturers - a material that combines the higher pressure performance of a PE100 material with the processing friendliness of a PE80. Borstar* HE3490-IM is a unique PE grade specifically for the injection moulding of PE100 pressure pipe fittings and provides greater consistency in overall quality and performance and has good flow characteristics with excellent strength.
Borstar HE3490-IM offers a wide range of production- and end-product advantages.
- Shorter cycle times: Can be injected at lower temperatures in comparison to conventional PE100 extrusion grade materials. The lower melt temperatures allow considerably shorter cycle times to be achieved, delivering cost benefits to the fittings manufacturer.
- Less scrap: Scrap rates can be reduced dramatically on fittings with intricate design, reducing the complexity of the moulding and inspection schemes, resulting in improved production efficiency and cost-effectiveness for the manufacturer.
- Improved mechanical properties: For small and complex fittings, considerable improvements to mechanical properties in the critical areas such as intersections and flow-front interfaces can be achieved enhancing the performance of the finished fitting.
- Improved surface finish: Due to the easy-flow properties of Borstar HE3490-IM, the surface quality of fittings is greatly improved when compared to fittings manufactured from conventional PE100 materials.
- Less warpage: Less ovalisation and warpage of the fittings results from the lower molecular weight of Borstar HE3490-IM, leading to greater consistency in quality and more reliable, better performing finished fittings.
- Easy processing: Borstar HE3490-IM processes like a PE80 material but the fitting performs as a PE100 product, which is exactly what manufacturers of fittings have been searching for since the introduction of PE100.
