Fire Retardant Engineering Process Improving
Fire retardant processing requests a skillfulness know-how of the compounding science：
■ Recent studies pointed out that processing parameters during the transformation of the polymeric materials （injection moulding extrusion…）Play a key rule on the fire properties
■ Major types of fire retardant need loading varying form 10 to 50% that lead the development of tailor made formulations. The shear stress and shear rate values generate thermo mechanical stresses that can degrade the polymer and modify its rheological behavior.
In order to guarantee your scale up phase and compatibility studies, CREPIM a full range of material dedicated to polymer transformation: counter and corotative twin screw extruders, injection moulding machines, blenders dedicated to thermoplastic & rubber ，material…
A wide range of integrated solutions can be delivered to customer, including the purchase of the raw material, the compounding and performance assessment, and to the final scale up studies. The partnership that we propose to our partners guarantee a complete follow up of the formulation during the production launch and during the formula evolution
