| Introduction of UHMW PE |

Dunone UHMWPE products originate with the higest grade resins,the molecular weight are at least up 3 million . During the processing from resin to final product,traditional method may cause the degrade of long chain structure of molecular and lower density of extruded products,but Dunone has the special technology to assure all products exhibit optimize properties with a minimum degrade on molecular weight,extruded products have the same high density as the compressed. Dunone UHMWPE products are manufactured from only the finest 100% pure resin without any additives or fillers.Standard color is unpigmented white or "natural",accepted by USDA/FDA.Other colors,additives or fillers combined are available on request. Introduction of UHMW PE/UHMW-PE/UPE UHMWPE is a linear polyethylene with a molecular weight more than 3 million.It is an outstanding plastics with the best selfubrication,impact absorbing properties and the highest resistance to abrasion,impact, chemicals of any thermoplastics polymer.It is regarded as an amazing material,otherwise the ultra long molecular chain make it difficult for processing,it cannot flow at melting,traditional methods don't work,so developing advanced conversion technology UHMWPE the star of the new material will grow fast and be widely used. UHMW-PE's main properties: 1. Impact strength UHMW-PE has the highest impact strength of any engineering plastics,about three times that of nylon,two times that of PC,five times that of ABS,withstands repeated impaction,even at -196℃ it is tough,together with it's superior abrasion and corrosion resistance.UHMW-PE has made itself idealy suited for industrial applications in complicate and rough environments. 2. Light weight and easily machined UHMW-PE is lighter than water,weighs approximately 1/8 that of steel,the same part UHMWPE has lower price than steel,need no maintain,easy to machine,conventionally sawed,milled,planed and drilled,so UHMWPE has a competitive price. 3. Abrasion resistance UHMW-PE's abrasion resistance beat any plastics even steel. Sand slurry abrasion test:
4. Selflubrication UHMW-PE is selflubricant,as a bearing even without grease it works better than steel or bronze bearing with grease, UHMW-PE friction parts need no lubricant,maintain easily,operate smoothly,have least friction,and cause no damage to oponent,is a superb material for use wear parts in machinery and equipment.
5. Noise and vibration absorbing UHMWPE has the best impaction absorbing property,so it dampen noise and vibration soundly. 6. Non-caking and sticking UHMW-PE's surface absorption affinity is very feeble,materials are difficult to stick to it. UHMW-PE's water absorption is less than 0.01% only 1% that of nylon66,in water environment it's very stable,resists the attachment of algae and fungus. 7. Sanitary UHMW-PE's FAD/USDA approved,can contact drug and food directly. 8. Anticorrosion and electrical insulation UHMW-PE exhibits excellent overall solvent characteristics except for very strong oxide acid and certain solvents. Applications As an excellent new material,UHMW-PE finds applications quickly and successfully.In the field of abrasion, selflubrication,impaction,vibration,corrosion,nonsticking etc,it's the best material for the substitution of bronze and nonferrometal,stainless steel,other engineering plastics,rubber and leather etc.It is commonly used as gears,sprokets,rollers, mixer paddles, pump impeller,bearing,chain and belt guides,wear strips etc. In material handing systems,UHMW-PE tubes and liners of container refuse blocking and sticking of materials,eliminating the need of vibration and clean-out. In the bottling and canning line of food and drug,it prevents abrasion and wear on cans and bottles,reduces noise,prolongs the life of screw and transportation belt. A list of industries successfully utilizing UHMW-PE Textile,chemical,oil ,field,mining,metallurgy,power station,marine,mechanical,paper,farming equipment,food processing,packing and bottling equipment,transportation,material handling,waste water treatment,recreation products. |
