一、聚丙烯（PP）
1、 Polypropylene (PP)
抗冲击能力差（在高载重条件下容易断裂），强度好，耐侯（抗老化，抗紫外线等）时间短，耐高温，收缩率小，托盘行业很少使用。
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、拉丝薄膜料
2、 Drawing film material
拉丝薄膜料托盘的机械强度约为共聚聚丙烯料托盘的百分之七十左右，虽然韧性好，但是在使用过程中容易发生弯曲，透光和抗表面老化性能不及共聚聚丙烯料托盘，如果在制造薄膜料托盘时没有添加足够的抗老化材料，时间稍长就容易在强烈的阳光下过早地发生表面龟裂、脆化等现象。薄膜料制造出的托盘透气性及传导热量的速度都比共聚聚丙烯大，也就是说再冬天容易变脆，从而在使用过程中容易发生断裂等现象，在无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：高密度低压聚乙烯（HDPE）其特点是：耐候（即：抗老化，抗紫外线等）时间长；强度较好，抗冲击能力适中；但耐低温性能差，低温或超负荷使用及撞击的情况下易发生断裂；收缩率较大，温差过大或周转频繁易老化过快。
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)
为了更好的满足客户的需求，威海都程塑料有限公司于2005年初研制成功以共聚聚丙烯为原材料的托盘。此材料又称改性聚丙烯（EPS30R），是在聚丙烯分子中添加聚乙烯的分子单体，使其性能兼具了以上两种原材料的优点，达到做载重塑料托盘的标准；并使使用寿命延长8-15年。共聚聚丙烯特点是：抗冲击性能强，强度较好，也就是说由此材料制造出的托盘韧性强，同时又不容易发生弯曲；耐低温，耐候（抗老化，抗紫外线等）时间长，收缩率小。在北方地区，冬季气温低，且冬夏温差大，容易使塑料托盘变脆发生断裂，加快老化速度；而共聚聚丙烯托盘正是弥补这一不足，从而达到更好的使用效果，也就从根本上降低了使用成本，是托盘行业更新换代的材料。
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
回收塑料制作的托盘，颜色较暗，低廉，但其耐候（抗老化，抗紫外线等）时间短，强度较弱，抗冲击能力差，耐低温性能差（受力容易断裂，使用周期短），使用成本远高于前三种材料。
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.
