PP Sheet is a kind of sheet made from polypropylene as the main raw material. Polypropylene is a semi-crystalline thermoplastic plastic with good comprehensive properties, and PP Sheet is widely used in numerous fields such as packaging, construction, and chemical engineering.
-
Low Density and Light Weight
PP Sheet has a relatively low density and is lighter in weight compared to some other engineering plastic sheets. This characteristic gives it an advantage in application scenarios where weight is a concern. For example, in certain lightweight structural components in the aerospace field or packaging materials that need to be frequently handled, it can reduce the overall weight, thereby lowering transportation costs and operational difficulties.
-
Good Chemical Stability
It shows relatively good tolerance to most chemical substances, including many common acid-base solutions (within a certain concentration range) and organic solvents. In the chemical industry, it can be used to fabricate containers for storing and transporting chemical drugs, inner linings of reaction kettles, etc., effectively preventing chemical corrosion and ensuring the safety and stability of products.
-
Water Resistance
It has excellent water resistance and is almost non-absorbent. In applications where it is in a humid environment or in long-term contact with water, such as waterborne building facilities, components around swimming pools, and shells of water treatment equipment, it will not experience expansion, deformation, or performance degradation due to water absorption.
-
Good Thermal Properties
It has a relatively high melting point and heat distortion temperature, and can maintain relatively good physical properties under certain high-temperature environments. It performs well in application scenarios such as the high-temperature sterilization process in food processing and heat-resistant components near the engine compartment of automobiles, and can withstand a certain degree of thermal load.
-
Good Mechanical Properties
Although the hardness of PP Sheet is moderate, it has relatively good toughness and fatigue resistance. When repeatedly bent or subjected to a certain impact force, it is not easy to break. It can be used to manufacture products that require a certain degree of elasticity and durability, such as movable hinges and conveyor belts.
-
Non-toxic and Environmentally Friendly
The material itself is non-toxic, odorless, and pollution-free, meeting environmental protection requirements. It is widely used in fields with high requirements for hygiene and safety, such as food packaging and the shells of medical devices (non-critical contact parts), ensuring the health and safety of consumers.
-
Packaging Industry
As a packaging material, PP Sheet can be made into various packaging boxes, trays, and turnover boxes. Its characteristics of light weight, good chemical stability, and non-toxicity make it suitable for packaging various products such as food, drugs, and electronic components, which can not only protect the safety of products during transportation and storage but also meet the hygiene requirements of different industries for packaging materials.
-
Building Field
- Interior Decoration: It can be used to fabricate ceilings, partition walls, decorative lines, etc. Due to its certain flexibility and ease of processing, it can meet diverse design requirements. Meanwhile, the non-toxic and environmentally friendly characteristic ensures the indoor air quality.
- Waterproof Engineering: It has applications in aspects such as basement waterproofing and auxiliary materials for roof waterproofing layers, utilizing its water resistance and chemical stability to enhance the waterproof effect.
-
Chemical Engineering Field
It is widely used in the manufacturing and protection of chemical equipment, such as inner linings of reaction kettles, storage tanks, and pipelines, as well as corrosion-resistant floorings and guardrails in chemical workshops. It can resist chemical corrosion during the chemical production process, prolong the service life of equipment, reduce maintenance costs and safety hazards.
-
Automobile Industry
It is used to manufacture automobile interior parts, such as instrument panels, door interior panels, etc., as well as some non-critical heat-resistant components, such as small partitions near the engine compartment. Its good thermal properties, mechanical properties, and environmental protection characteristics meet the requirements of the automobile industry for material properties and safety.
-
Electronic and Electrical Field
In electronic and electrical products, PP Sheet can be used as a shell material or an internal support structural member. Its characteristics of light weight, good insulation, and non-toxic and environmentally friendly help to reduce the weight of products, improve safety, and meet the trend of miniaturization and lightweighting of electronic and electrical products.
