ELECTRICALLY CONDUCTIVE PLASTICS

Parker Chomerics PREMIER™ Electrically Conductive Plastics provide “immunity” for sensitive components from incoming electromagnetic interference (EMI) and/or prevent excessive emissions of EMI to other susceptible equipment.  

Product designers and engineers are discovering the unique advantages of electrically conductive plastics compared to traditional metals – such as weight reduction, cost reductions, elimination of secondary manufacturing steps – and this results in lean supply chains.

PREMIER PBT and PEI CONDUCTIVE PLASTIC PELLET GRADES
PBT is known for its excellent chemical resistance thereby making it an ideal material for environments that have exposure to automotive type fluids (gasoline, motor oil, glycol 50/50 mix, brake and transmission fluids).

PEI (aka “Ultem”) polymer material is UL V0 rated down to 1.8 mm wall thickness and has a special blend of conductive elements. This material meets the Boeing 7238 smoke density rating of MAX 110 Ds with 3.0 mm @ 4 minutes.

WHY ELECTRICALLY CONDUCTIVE PLASTICS

Parker Chomerics PREMIER ‘single pellet’ materials offer superior performance and consistency when compared to many electrically conductive plastic materials.  The primary advantage of PREMIER is the use of pultrusion compounding to ensure uniform amounts of conductive filler are within each pellet.

Our PREMIER products are manufactured as single pellet formulations, which ensures the most reliable, consistent shielding of molded products.

Single pellet or homogeneous products are far superior to multi-pellet blends (also called dry blends or salt-and-pepper blends) that use pellets from different compounds randomly mixed together.   

CLASS LEADING EMI SHIELDING CONSISTENCY FROM PART TO PART

Single pellet performance benefits are easily demonstrated when shielding performance is compared between dry blend materials and PREMIER single pellets in capability studies.  Our single pellet materials prevent the risk of poor EMI shielding – and this avoids potential failure in the field.
PREMIER SINGLE PELLETS
Single conductive fiber in every pellet leads to consistent EMI shielding performance.
MULTI-PELLET BLENDS
MULTI-PELLET BLENDS
Non-homogenous mix of conductive slugs and plastic pellets leads to uneven EMI shielding performance.

NO LIMITATIONS DUE TO PACKAGING SIZES

Dry blends (that use multiple pellet mixtures) have packaging limitations – they are sold only in smaller bags or containers, and carry the risk of the heavier pellets settling during transportation.  

When settling occurs, it results in inconsistency in shielding and mechanical performance.  Large volume programs can save significant labor hours by using single pellet products such as PREMIER.

UP TO 75% LESS WEIGHT

PREMIER's density at 1.2 to 1.4 g/cc is one-half the density of aluminum (2.7 g/cc).

PREMIER’s light weight, coupled with the ability to mold thinner walls, allows PREMIER parts to weigh up to 75% less.
