There are many types of plastics. Hundreds of resins are in industrial production. Nearly 40 are commonly used, and new ones are created every year. In the face of so many varieties, how to correctly choose the slip and anti-blocking masterbatch material, to meet the requirements of product performance and molding processing performance, is a complex system engineering.
The purpose of selecting the material is to ensure that the product can play a normal role in the process of use and has reasonable performance, appropriate processing performance, and the lowest economic expenditure. Therefore, the selection of plastic materials, concerning the following principles.
1. Physical principles of material selection for slip and anti-blocking masterbatch
The physical properties of the raw material should meet the requirements of use, which mainly refers to the following four points:
(1) The mechanical properties should meet the application requirements.
That is to say, in the process of product operation, stress types are required and materials are selected based on the correct analysis of stress states. This index is to choose the plastic material of slip and anti-blocking masterbatch raw material.
(2) Thermal properties should meet the requirements of use
Because plastic products are working at a certain ambient temperature, thermal properties should be considered in the design of material selection of slip and anti-blocking masterbatch.
(3) Food packaging should meet the requirements for the use of food packaging
With its safety standards, so the selection of slip and anti-blocking masterbatch must be considered in the material.
2. No toxic materials can be used as a slip and anti-blocking masterbatch
The chemical stability of the material should meet the requirements of use. Due to the wide variety of raw materials and the ever-changing working environment, materials should be selected according to the specific working environment of the product to ensure the normal work of the product.
3. slip and anti-blocking masterbatch should be suitable for manufacturing
When selecting materials, the adaptability of materials to the manufacturing process should be fully considered and satisfied.
4. The economic benefit of the opening slicker should be optimized
In the selection of materials, one should consider as far as possible reducing the cost of plastic products to achieve economic optimization benefits.
5. The slip and anti-blocking masterbatch should be packaged and safe
According to the product characteristics of food packaging, it mainly involves the following problems:
(1) Safety problem
According to the production experience of the slip and anti-blocking masterbatch manufacturer, slip and anti-blocking masterbatch should meet the requirements of the environment, green environmental protection, and so on.
Therefore, the selected materials should have the characteristics of transparency, environmental protection, and non-precipitation.
(2) Health and safety issues
Some products, such as electrical appliances used as kitchenware, and food packaging materials, will directly or indirectly contact with food, the selection of such products should consider the stability and toxicity of the material itself, as well as the toxicity and mobility of residual monomer, plastic additives, fillers, etc., and the selection of materials in line with health and safety regulations.
