Development of Polymer ADDITIVE

Development of Polymer ADDITIVE. Three types of aditif: Antioxidant, slip and clarifying the lately a lot of different applications used in the polyolefin polymer discussed in this paper. Antioxidant role as a prophylactic radical formation and hidroperoksida The disclosed with the hope to provide an understanding of chemical substances-substances that can act as an Antioxidant. Antioxidant such as the type of commercial irganox 1010, irgafos PI68 and types of the other new and shows a combination of rapid growth in this industry aditif. Slip agent used most of the blown film applications. One of the plastic packaging which is very large in dikonsumsinya Indonesian. Currently the most widely used as an agent is oleamida Slip and urikamida. PE uriakamida use more often, because it has a high stability termallebih. In the past many also used stearamida and other wax, but this time have left because of the need coefficient of friction is lower. Aditif ago in the source this came from animal bones, but later, especially in Indonesia and other Muslim countries shifted to the vegetal source. Aditif third Clarifying the agent is covered or also known as Nucleating agent. Particularly widely used for Polipropilen kopolimer random. Both the application and Injection Molding Blow Molding. Aditif this substance can increase the transparency of the application Polipropilen so Extrusion stretch blow
molding, polymer Polipropilen a semikristalin can setrasparan PET packaging amorf on betel. The main source of aditif this is Sorbitol. However, until now only one supplier that is capable of aditif create this harmony with nature tranparasi and organoleptic nature. Last reviewed also about the legal aspects of the polymer, especially in aditif restriction through specific migration limits FDA-USA, while more emphasis on some extract maximum solvent with the condition specific.

ADVANTAGES OF PVC -ITS MERIT-

Polyninyl chloride (PYe) was first manufactured in 1931 as a robust and lightweight new plastic. This breaktrought materials was brought about to substitute public lifelines such as water supply, sewage pipes, or power lines. It is also used in building materials such as sidings, flooring and roofing sheets, or parts for automobile and home electrical appliances. Consumer PYC products include food wraps, synthetic lather and stationary. As you can see, PYC is used in a vast range of applications to support everyday life. 25 mil1ion tons ofPYC is used around the globe today, both in industrialized and developing countries, due to its cost efficiency, durability, processability and resource saving features.

POTENCY NATURAL MATERIALS Polymer as a raw material

Of the present plastic or synthetic polymer, the main raw material is oil, a material that is not can be renewed. Therefore, the need to search for new sources altematif, the natural plant material. Plastic materials derived from plants or green plastic in the country ahead of the start-poli laktat acid (PLA) and poli-hidroksi alkanoat (PHA) through the fermentation process, but the processes are still expensive, so the need to look for other ways. A natural polymer derived directly from the plant is natural rubber, cellulose from cotton, wood products, bamboo, rami, plants, fruit (pineapple, banana). Polymer is another source of marine and animal sources, such as shrimp, leather, crab skin, sheep wool and silk worm. Generally these products environmentally friendly. Indonesian have raw materials, but utilization of industrial products are still in the initial stage. (N. M. Surdia; Departemen Kimia, ITB)
