Technomelt & Macromelt resins

The low pressure resins including PA (Polyamide), PO (Polyolefin) and PUR Hotmelt . Key components of the process are specialized molding equipment and raw materials. Dimer acid-based macromelt materials, (also referred to as hotmelt) are what acts as molding materials. The materials become less vicious when heated and they can be re-shaped and later harden to attain the desired form when cooled. Compared to other materials, this macromelts are particularly suited for low pressure molding because of two main reasons

• Low-viscosity during processing at low temperature which requires low injection pressure, a very important property when it comes to over-molding sensitive electronic components.
• High performance adhesive property, which is purely mechanical with no chemical reaction involved.
