Material analysis of double-layer stainless steel thermos cup lid

First, the types and characteristics of plastic materials
The commonly used plastic materials for double-layer stainless steel thermos cup lids are PP, PE, PS, etc. Among them, PP material has good heat resistance and hardness, and is suitable for use at high temperatures; PE material has good elasticity and good sealing, and is suitable for occasions with high sealing requirements; The PS material is light in weight and high in transparency, and is suitable for occasions with high appearance requirements.
Second, the advantages and disadvantages of the material
1. PP material: the advantages are high hardness, wear resistance, and not easy to deform; The disadvantages are poor impact resistance, easy cracking and cracking.
2. PE material: the advantage is good sealing and easy plastic processing; The disadvantage is that it is easy to age and has poor heat resistance.
3. PS material: the advantages are light weight, high transparency and smooth surface; The disadvantage is that it is brittle and not easy to process.
3. Precautions
1. When choosing a double-layer stainless steel thermos cup lid, you should choose a product with good taste and good quality;
2. When using, care should be taken not to place the lid in a high-temperature environment for a long time to avoid deformation or odor;
3. Wash and dry in time after each use to avoid bacterial growth.
In short, different materials are suitable for different occasions and uses, and the specific choice should be determined according to your own needs. At the same time, attention should be paid to protection and proper use to prolong its service life.
