The American company Willow Ridge Plastics and ECM BloFilnm claim to have developed a method for effectively degrading polyethylene (PE) and polypropylene (PP) products by adding a special additive masterbatch to a polyolefin (PE) carrier to make polyolefin products possible. Fully biodegradable within 5 years, its product cost price is comparable to ordinary LDPE and PP.
Comparing with the price of the original biodegradable polymer, biodegradable copolyester and lactic acid polymer, the polyolefin additive masterbatch is at least 10 times cheaper than the average price per cubic inch.
ECM sells a patented biodegradable additive. This additive uses LDPE as a carrier to make a masterbatch. The amount added is 1 percent in the production of the product. According to the degradation environment, PE and PP products are within 9 months to 5 years. Fully biodegradable. The use of ECM masterbatch plastics for a long period of time will result in decay and decomposition. The activity of the ECM masterbatch will cause a series of similar effects, causing the polyolefin mixture to bury or dispose of in the same amount of time as the waste, and degrade in a given amount of time.
The first commercial applications of biodegradable master batches will soon be available, including Irish trash bags, New Zealand bread bags, Indian milk bags and U.S. food packaging films.
One of three products of Willow Ridge's Polly Starch N is a LDPE containing 55% corn starch masterbatch. Starch content can generally be reduced to 12.5% ​​and 25%, suitable for garbage bags, plastic film and injection molding, blow molding products, processing aids and 3% -10% desiccant trade name Aquanil, to control the humidity of the masterbatch.
PDQ is another of the company's patented starch-free products that promote photo- and thermal-oxidative degradation of PE and PP. The amount of PDQ added - generally 3%, the price is 2.25 US dollars. In agricultural applications, this additive can be applied to black and dark black plastic film and transparent solar film. Other uses include garbage bags, injection molded products, etc.
Another series of Willow Ridge's photodegradable masterbatch UV-H accelerates UV degradation by generating free radicals because free radicals can separate long polymer chains into smaller segments that can attack microorganisms. UV-H is typically used. At 2%, it can be mixed with PDQ in a three-dimensional operation equipment. The resulting mixture product is named PDQ-H.
Willow Ridge's additives can work alone or in combination with a variety of additives. For example: PDQ's thermo-oxidative effect can increase the product's temperature, accelerate the biodegradation process, starch biodegradation, plastic products will produce micro-holes To accelerate photodegradation.

With the way of carrying tents, arrived at the scene to be assembled, so that various parts and tools. Learn the names of all parts and using the method, the familiar Tent structure, can quickly and easily set up tents.
Structure:
Inside and outside the tent curtains, tent poles and the wind rope, nails.
Category:
Outdoor tent is divided into several categories: advertising tents (promotional tents), military tents (commercial tents, tents, gable top site) tent, tour tents {(Season 3 (ordinary tent outdoor activity) and 4 seasons (winter / Alpine tent use)} relief tents, inflatable tents, wash fire tent, children's play tent. Below we detail these tents. According to different ways can be divided into open open tent and hand tent.
Application:
The field work, training camp, temporary clubs, sports entertainment and military headquarters, field hospital, emergency rescue and disaster relief, camping, leisure, tourism and so on.
How to select the right tent:
Beware of recommendation tent when we buy a tent generally see Recommendation tents. These tents are often placed in a very eye-catching places, and the general price discounts are very attractive, but the tent is really recommended for you? The general taking the recommended tent there are two possibilities: one is this tent inventory, and sales are not ideal, so in order to make the products sold to add the recommended way to better sales, better cleaning up inventory. The second is this tent product is really sell well, but when you want to buy it will be supporting associated with many peripheral products. So this is not to sell the business tent, but this product in the selection of merchandise, so we recommend tents, attention must be paid to the products in the market is really hot. Beware of the tent The business to play the writing skill for each businesses selling tents will have some words or pictures of the poster description, so as to make people fully understand the appearance of the tent, and the advantages and disadvantages, although we feel that this description is very detailed, so that they can quickly understand the need to buy a tent, but there are certain skills for general products, this often will be exaggerated, but in fact the function is not so complete, and they will in the text on the efforts to increase the function or effect. In fact, it is often very useful tricks, because we do not understand or know of the tent, so after businesses are described, it will become the product to some of the sky effect.
