What is maleic anhydride grafted polypropylene?
Maleic anhydride–grafted polypropylene (MAgPP) is a compatibilizer which is very effective and commonly used for natural fiber and polymer matrix at the interface. However, the flexural strength increases and impact strength decreases with increasing content of fibers, due to the high stiffness of fiber.
What is maleic anhydride grafted polyethylene?
Maleic anhydride (MA) grafted PE, MA-g-PE, is very important in the enhancement of compatibility between nonpolar PE and natural polar materials like cellulose and chitin. The modifications of PE with MA through a free-radical reaction in both solution and melt processes have been widely investigated.
Is maleic anhydride an acid?
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Maleic anhydride is an organic compound with the formula C2H2(CO)2O. It is the acid anhydride of maleic acid. It is a colorless or white solid with an acrid odor.
What is PE G Ma?
Materials. PE-g-MA (Polyethylene-graft-maleic anhydride) is a compatibilizer for polymer blends which serves as support for polar to nonpolar substances.
Where is maleic anhydride used?
Maleic anhydride is used in the production of unsaturated polyester resin as well as in the manufacture of coatings, pharmaceutics, agricultural products, surfactants, and as an additive of plastics.
What is PP G Ma?
Abstract. Polypropylene (PP) functionalized with maleic anhydride (PP-MA) has been used as compatibilizer for PP/nylon blends. PP functionalized with glycidyl methacrylate (PP-GMA) should be a good alternative due to the reactivity of the epoxy group with –NH2 and –COOH groups.
What is SEBS G Ma?
RPET: recycled polyethylene terephthalate; HDPE: high-density polyethylene; SEBS-g-MA: maleic anhydride- grafted styrene–ethylene/butylene–styrene.
Why is maleic anhydride important?
Maleic anhydride is essential to the production of a multitude of resins and plastics, agricultural and industrial chemicals, petroleum additives, paper sizing, water treatment chemicals, epoxy curing agents, artificial sweeteners, flavor enhancers, hair sprays, pharmaceuticals and copolymers.
What is a PP material?
Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles.
What is the functional group of anhydride?
An acid anhydride is a type of chemical compound derived by the removal of water molecules from an acid. In organic chemistry, organic acid anhydrides contain the functional group R(CO)O(CO)R’.
What is PP used for?
Due to its low cost and flexibility, PP is used in various packaging forms and has replaced traditional materials such as paper, cellophane, and paper. It is widely used to make pallets, bottles, jars, yogurt containers, hot beverage cups, food packing, etc.
What is the reaction temperature of grafted polymers?
GRAFT POLYMER PRODUCTS COMPETITORS PRODUCTS Grafting reaction temperatures are low, at the melting temperature of polymers (140°C- 150°C for polyolefin) No material degradation, awhiter color of grafted material and no additional antioxidants are present.
What is the graftabond™ type reactive monomer grafting degree?
GRAFTABOND™ Type Reactive Monomer Grafting Degree [\%] PET/PE 1/5 of PE PA/PE 1/5 of minor component PA/PP 1/5 of minor component PLA/PP 1/5 of minor component PLA/PE 5-10 \% of chosen grades PC/ABS alloys 5 \% of chosen grades PC/PBT alloys 5-10 \% of chosen grades HD-MAH 02030 C MAH 2,5-3 HD-GMA 02530 C GMA 2,5-3
Does the color of the grafted material affect the final product?
White grafted material Doesn’t affect final product color Yellow grafted material May influence final material’s color The versatility of Grafting Monomers
How does grafting reduce the need for compatibilizers?
By grafting higher amounts of MAH, we substantially reduce the quantity required to achieve good compatibility: Up to 60\% less compatibilizers required Grafting degree up to 2\%, with many unreacted monomers present Very slight MFI reductionwhen comparing grafted materials to virgin material. (PE) MFI Decreases from 8 g/10min to 6 g/10min
