In Nylon-6 film applications, FINAWAX-C is also used as a slip and anti-blocking agent.ENGINEERING PLASTICS
Producing adequate lubrication in engineering plastics presents problems not ordinarily found with regular plastics. The most common problem is finding a suitable product that will produce the desired effect and withstand the high temperatures needed to process these materials. The problem of lubrication and flow control becomes very demanding in case of highly filled polymers and their blends.The processing conditions required to produce outstanding engineering plastics are just too intense for most of the common lubricants. For such applications FINAWAX-C has been engineered for engineering plastics
FINAWAX-C provides superior lubrication even at temperatures upto 260บ C. FINAWAX-C remains stable at processing temperature and maintains its performance when such polymers are reground and processed again. Its controlled compatibility provides good lubrication and release effect during processing. Due to its chemical nature and high stability, FINAWAX-C does not influence basic specifications of the polymer in which it is added.
In processing of engineering thermoplastics like POLYAMIDES and POLYACETAL, a great extent of improvement in flow properties can be achieved by FINAWAX-C . This makes it possible to produce very complex injection molded articles from these plastics. Generally 0.2 - 0.5 phr of FINAWAX-C is used.
Immediately after processing THERMOPLASTIC POLYURETHANE (TPU) displays strong surface tackiness which hinders the release of injection molded articles from the mold and causes them to stick together when stacked. Use of 0.3 - 1.0 phr FINAWAX-C facilitates remolding and reduces blocking of articles when stacked.
THERMOPLASTIC POLYURETHANE
This elastomer is very sticky immediately after processing. As a result, injection molded articles are difficult to remove from the mold and block on stacking during thermoplastic PU extrusion.The inside of extruded hose sticks together on rolling and cannot be reopened easily FINAWAX-C is useful in such applications as an internal release agent. Recommended dosage is 0.5% - 1.0%.
THERMOSETTING RESINS
The versatility of FINAWAX-C is demonstrated by its use not only in thermoplastic injection molding formulations, but also in the thermoset molding and potting compounds.Thermosetting compounds eg., PF, UF, MF need effective lubricants and mold release agents. This is particularly very relevant in mineral and fiberous material filled PF compound and especially formulated for MF compounds for molding large surface area articles like table wares.
FINAWAX-C if incorporated in such thermosets offers considerable advantage in filling intricate mold cavities and improves surface finish. Recommended dose level is about 1.0% to 1.5%.
FINAWAX-C addition increases output by reducing molding cycle time and helps to reduce electrical power consumption by modifying the melt viscosity of thermosets while processing.
In color concentrates for PS and ABS with a polymer carrier; FINAWAX-C functions as a wetting agent and viscosity modifier. FINAWAX-C is added at the level of 3-5% based on the weight of the polymer.
FINAWAX-C is also suitable as a sole carrier for high % concentrates of basic pigment used for blending with PS/ABS and other engineering thermoplastics.
FINAWAX-C is an excellent pigment dispersing agent for resin systems. Colored pigment or carbon black are put into the most suitable melted FINAWAX-C and then pelletized or solidified and cut or broken into small pieces. The pellets or pieces are put into the resin system at 1% to disperse pigments through the resin.
FINAWAX-C As Compatibilizer In Polymer Blends And Alloys:
FINAWAX-C as a compatibilizer makes it possible to blend what are normally incompatible polymers. By allowing these components to intermix, one can achieve a homogeneous plastic compound with desired properties.
