COMPARING THERMOPLASTICS AGAINST METALS - MECHANICAL PROPERTIES


THE COEFFICIENT OF LINEAR THERMAL EXPANSION (CLTE) FOR PLASTICS IS 4 TO 8 TIMES HIGHER THAN OTHER ENGINEERING MATERIALS. MATCHING THE CLTE VALUES OF VARIOUS PLASTICS TO THAT OF ALUMINUM (1.2) AND STAINLESS STEEL (0.9) WILL KEEP SENSITIVE ELECTRONIC DEVICES LIKE DISK DRIVES, PRINTERS, AND BEARING APPLICATIONS IN PEAK OPERATING CONDITION. USING PLASCOÕS LITERATURE, HERE ARE A FEW COMPOSITES WORTH CONSIDERING IN FUTURE APPLICATIONS:


MATERIAL PLASCO CLTE VALUE X 10 (-5)
PBT +30%GF PBF 600 1.2
NY 6/6 +30%CF PNC 600 1.2
PSUL +40%GF PHF 800 1.2
PC+40%GF+15%PTFE TCF 803 1.2
PC +30%CF PCC 600 0.9
PEI +40%GF PZF 800 0.9
NY 6/6 +40%CF PNC 800 0.9


THE FOLLOWING SERIES OF THERMOPLASTIC COMPOUNDS OFFER THE HIGHEST VALUES FOR TENSILE STRENGTH AVAILABLE ON TODAY'S MARKET. THE PLASCO MATERIALS ARE BASED ON CONVENTIONAL SHORT FIBER TECHNOLOGY. POLYMER COMPOSITES' COMPOUNDS ARE BASED ON PULTRUSION TECHNOLOGY. BOTH PRODUCT LINES ARE AVAILABLE THROUGH PLASCO INC.


MATERIAL SUPPLIER & CODE TENSILE STRENGTH
NY6 / 6+40%CF PLASCO PNC 800 40,000 PSI
PEI +40%GF PLASCO PZF 800 32,000 PSI
PEI +40%CF PLASCO PZC 800 37,000 PSI
NY6 / 6+60%GF PCI N66GL -60-001 40,000 PSI
PUR +60%GF PCI PUGL -60-001 34,000 PSI
NY6 / 6+60%CF PCI N66CF -60-001 52,000 PSI *
PC +50%CF PCI PCCF -50-001 33,000 PSI *
* DENOTES EXPERIMENTAL VALUES
