詳細內容： ①PC KGN-20MRAPP HAS EXCEPTIONAL CHEMICAL RESISTANCE, ACID RESISTANCE, AND ALKALI RESISTANCE. CAPABLE OF PRODUCING HIGH-PURITY PP; USED IN THE SEMICONDUCTOR INDUSTRY. IT IS ALSO RESISTANT TO BACTERIAL PRODUCTION AND IS SUITABLE FOR USE AS DISPOSABLE SYRINGES AND MEDICAL EQUIPMENT. CAN BE USED FOR INJECTION MOLDING OR MACHINING AND WELDING. CAN BE USED FOR PLASTIC PIPES, FILTER MATERIALS, MICROPHONES AND OTHER QUALITY REQUIREMENTS HIGHER THAN POLYETHYLENE PRODUCTS. THE BILL IS MADE BY BIAXIAL STRETCH PP (BOPP), SO ITS DURABILITY IS IMPROVED. POLYPROPYLENE WAS DISCOVERED BY THE ITALY CHEMIST GIULIO NATTA IN THE EARLY 1950. IN MODERN SCIENCE, THE INVENTION OF A THING MAY BE INVENTED IN DIFFERENT PLACES AT THE SAME TIME. POLYPROPYLENE IS SUCH AN EXTREME EXAMPLE THAT IT WAS INDEPENDENTLY INVENTED ABOUT NINE TIMES. IT IS THE DREAM OF A PATENT LAWYER AND LITIGATION SCRIPT, TO 1989 ENDED. POLYPROPYLENE HAS BEEN TRYING TO CONTINUE THE LEGAL SERIES, AND TWO AMERICAN CHEMISTS, J. PAUL HOGAN AND ROBERT BANKS, WHO WORK AT PHILIP OIL, ARE NOW CONSIDERED TO BE THE INVENTORS OF THE MATERIAL. LIKE ITS COUSIN POLYPROPYLENE POLYETHYLENE, VERY CHEAP AND PLENTIFUL SUPPLY. PRODUCTS RANGING FROM PLASTIC BOTTLES TO CARPETS AND PLASTIC FURNITURE ARE ALSO USED IN THE AUTOMOTIVE INDUSTRY. PP/3719/ SCHULMAN PP/2407/ SCHULMAN PLASTIC PLASTIC??

THE MATERIAL ITSELF IS NON-TOXIC, IT IS BISPHENOL A INTO PC MATERIAL "WHEN IF THE CONVERSION IS NOT COMPLETE, SO WHEN THE TEMPERATURE IS LIKELY TO RELEASE BISPHENOL A TOXIC, CAN CAUSE CANCER. OUR COUNTRY HAS BEEN A LOT OF REPORTS. PROHIBITION OF INFANT FOOD CONTAINER PRODUCTION IN SEPTEMBER 1ST BANNED THE SALE OF BISPHENOL A FROM JUNE 1ST OF THIS YEAR. THE DISSOLUTION OF HARMFUL SUBSTANCES IN FOOD GRADE PP IN NORMAL AND HIGH TEMPERATURE CONDITIONS. BUT NOT ORDINARY PLASTIC IN ROOM TEMPERATURE OR HIGH TEMPERATURE WILL RELEASE HARMFUL SUBSTANCES, HARMFUL TO HUMAN HEALTH." 07 "PC" AND OTHER COMMON USES: KETTLE, CUPS, BOTTLES AND OTHER COMBUSTIBLE POM WHITE CRYSTALLINE POWDER, WITH THE SMELL OF FORMALDEHYDE. SLOWLY DISSOLVE IN COLD WATER, DISSOLVE QUICKLY IN HOT WATER. SOLUBILITY IN WATER AT 20 0.24G/100CMHO. INSOLUBLE IN ETHER. SOLUBLE IN CAUSTIC SODA, POTASSIUM SOLUTION. GENERAL PERFORMANCE POM IS A SMOOTH, SHINY, HARD AND DENSE MATERIAL, YELLOWISH OR WHITE, WITH A THIN TRANSLUCENT PART. THE COMBUSTION CHARACTERISTICS OF EASY COMBUSTION, THE FIRE CONTINUED TO BURN AFTER THE FLAME IS YELLOW, THE UPPER, LOWER BLUE, MELT DRIPPING, THERE IS A STRONG PUNGENT SMELL OF FORMALDEHYDE, FISHY. POM IS WHITE POWDER, GENERALLY OPAQUE, GOOD COLORING, 1.41-1.43 GRAMS / CUBIC CENTIMETER, MOLDING SHRINKAGE RATE OF 1.2-3.0%, MOLDING TEMPERATURE OF 170-200 DEGREES, DRYING CONDITIONS 80-90 HOURS, 2 HOURS. THE LONG-TERM HEAT RESISTANCE OF POM IS NOT HIGH, BUT THE SHORT-TERM CAN REACH 160 DEG C, THE HOMOPOLYMERIZATION OF POM COPOLYMER POM HIGH SHORT-TERM HEAT THAN ABOVE 10 DEGREES, BUT THE LONG-TERM HEAT POM COPOLYMER RATHER THAN HOMOPOLYMER POM HIGH TEMPERATURE OF ABOUT 10 POM 100PE BK, POM 100PE, NC POM, 100ST BK, POM 100ST, NC, POM, 100STE NC, POM 100T BK PC "IS A WIDELY USED MATERIAL, ESPECIALLY FOR MANUFACTURING BOTTLES, SPACE CUP, BECAUSE OF CONTAINING BISPHENOL A AND CONTROVERSIAL. EXPERTS POINTED OUT THAT, IN THEORY, AS LONG AS IN THE PRODUCTION PROCESS OF THE PC II, BISPHENOL A 100% INTO PLASTIC STRUCTURE, THEN SAID NO PRODUCTS OF BISPHENOL A, NOT TO MENTION THE RELEASE. BUT, IF THERE IS A SMALL AMOUNT OF BISPHENOL A HAS BEEN CONVERTED INTO PLASTIC STRUCTURE PC ", MAY BE RELEASED INTO THE FOOD OR DRINK. THEREFORE, IN THE USE OF THE PLASTIC CONTAINER TO CONTAIN FOOD IN STRICT ACCORDANCE WITH THE INSTRUCTIONS; STORAGE AND DISINFECTION IN THE RIGHT WAY; TO AVOID REPEATED USE OF AGING OR DAMAGED PRODUCTS, PC.
