1、 Polypropylene (PP)

抗沖擊能力差（在高載重條件下容易斷裂），強(qiáng)度好，耐侯（抗老化，抗紫外線等）時(shí)間短，耐高溫，收縮率小，托盤行業(yè)很少使用。

Low impact resistance (easy to fracture under high load conditions), high strength, resistance to aging (anti aging, UV resistance, etc.), short time, high temperature resistance, low shrinkage, and pallet industry is seldom used.

二、拉絲薄膜料

2、 Drawing film material

拉絲薄膜料托盤的機(jī)械強(qiáng)度約為共聚聚丙烯料托盤的百分之七十左右，雖然韌性好，但是在使用過(guò)程中容易發(fā)生彎曲，透光和抗表面老化性能不及共聚聚丙烯料托盤，如果在制造薄膜料托盤時(shí)沒(méi)有添加足夠的抗老化材料，時(shí)間稍長(zhǎng)就容易在強(qiáng)烈的陽(yáng)光下過(guò)早地發(fā)生表面龜裂、脆化等現(xiàn)象。薄膜料制造出的托盤透氣性及傳導(dǎo)熱量的速度都比共聚聚丙烯大，也就是說(shuō)再冬天容易變脆，從而在使用過(guò)程中容易發(fā)生斷裂等現(xiàn)象，在無(wú)形中也就增加了使用成本。

The mechanical strength of the wire drawing material pallet is about seventy percent of that of the polypropylene polypropylene pallet. Although the toughness is good, it is prone to bend in the course of use, and its transmittance and surface aging resistance are not as good as that of the polypropylene polypropylene pallet. If there is not enough anti aging material when making the film tray, it will happen easily in a strong sunlight for a longer time. Surface cracking, embrittlement and other phenomena. The air permeability and heat conduction speed of the tray made of film material are higher than that of copolypropylene, that is to say, it is easy to become brittle in winter, so it is easy to fracture and other phenomena in the use process, which will increase the use cost virtually.

三、聚乙烯（HDPE）

3、 Polyethylene (HDPE)

即：高密度低壓聚乙烯（HDPE）其特點(diǎn)是：耐候（即：抗老化，抗紫外線等）時(shí)間長(zhǎng)；強(qiáng)度較好，抗沖擊能力適中；但耐低溫性能差，低溫或超負(fù)荷使用及撞擊的情況下易發(fā)生斷裂；收縮率較大，溫差過(guò)大或周轉(zhuǎn)頻繁易老化過(guò)快。

That is: high density low pressure polyethylene (HDPE) is characterized by weathering (i.e., anti-aging, UV resistance, etc.) for a long time. The strength is good and the impact resistance is moderate. However, it has poor resistance to low temperature, prone to fracture under the condition of low temperature or overload and impact. The shrinkage rate is large, the temperature difference is too large or the turnover is frequent and the aging is too fast.

四、共聚聚丙烯（EPS30R）

4、 Polypropylene copolymer (EPS30R)

為了更好的滿足客戶的需求，威海都程塑料有限公司于2005年初研制成功以共聚聚丙烯為原材料的托盤。此材料又稱改性聚丙烯（EPS30R），是在聚丙烯分子中添加聚乙烯的分子單體，使其性能兼具了以上兩種原材料的優(yōu)點(diǎn)，達(dá)到做載重塑料托盤的標(biāo)準(zhǔn)；并使使用壽命延長(zhǎng)8-15年。共聚聚丙烯特點(diǎn)是：抗沖擊性能強(qiáng)，強(qiáng)度較好，也就是說(shuō)由此材料制造出的托盤韌性強(qiáng)，同時(shí)又不容易發(fā)生彎曲；耐低溫，耐候（抗老化，抗紫外線等）時(shí)間長(zhǎng)，收縮率小。在北方地區(qū)，冬季氣溫低，且冬夏溫差大，容易使塑料托盤變脆發(fā)生斷裂，加快老化速度；而共聚聚丙烯托盤正是彌補(bǔ)這一不足，從而達(dá)到更好的使用效果，也就從根本上降低了使用成本，是托盤行業(yè)更新?lián)Q代的材料。

In order to better meet the needs of customers, Weihai Ducheng Plastics Co., Ltd. successfully developed a pallet with copolypropylene as raw material in early 2005. This material, also known as modified polypropylene (EPS30R), is a kind of molecular monomer added with polyethylene in polypropylene molecules, which makes its performance have the advantages of the above two raw materials, reaching the best standard for making load-bearing plastic pallet, and prolonging the service life to 8-15 years. The characteristics of copolymerized polypropylene are: strong impact resistance and good strength. That is to say, the tray made of this material is strong in toughness, and it is not easy to bend at the same time. It has low temperature resistance, weathering resistance (anti aging, UV resistance, etc.) and has a low shrinkage rate. In northern China, the low temperature in winter and the large temperature difference between winter and summer can easily make the plastic tray brittle and fracture, and accelerate the aging speed; and the copolypropylene tray is to make up for this deficiency, so as to achieve the best use effect, and fundamentally reduce the use cost, which is the preferred material for pallet industry upgrading.

五、回收塑料

5、 Recycled plastics

回收塑料制作的托盤，顏色較暗，低廉，但其耐候（抗老化，抗紫外線等）時(shí)間短，強(qiáng)度較弱，抗沖擊能力差，耐低溫性能差（受力容易斷裂，使用周期短），使用成本遠(yuǎn)高于前三種材料。

The tray made of recycled plastic is dark in color and low in price, but its weatherability (anti-aging, UV resistance, etc.) is short, its strength is weak, its impact resistance is poor, its low temperature resistance is poor (stress is easy to fracture, and its use cycle is short), and its use cost is much higher than that of the first three materials.
