Polystyrene (PS) material is a popular choice for carrier tape raw material due to its unique properties and formability. In this article post, we will take a closer look at PS material properties and discuss how they affect the molding process.
PS material is a thermoplastic polymer used in various industries such as packaging, electronics and automotive. In carrier tape production it is an excellent choice due to its economy, rigidity and heat resistance.
When using PS material as carrier tape raw material, it is necessary to understand its characteristics. First, PS is an amorphous polymer, meaning it has no apparent crystalline structure. This characteristic affects its mechanical and thermal properties, namely stiffness, brittleness, opacity and heat resistance.
The unique combination of properties of PS materials make them ideal for the electronics industry. Specifically, its moisture resistance ensures protection of electronic components during transport or storage. That’s why PS material is a popular choice for carrier tape raw material.
Another important aspect of PS material is its formability. Thanks to its low melt viscosity, PS has excellent formability, enabling high-quality finishes and efficient processing times when producing carrier tape raw materials.
PS molding performance
1. Amorphous material has low moisture absorption, does not need to be fully dried, and is not easy to decompose, but has a large thermal expansion coefficient and is prone to internal stress. It has good fluidity and can be molded with a screw or plunger injection machine.
2. It is appropriate to use high material temperature, high mold temperature, and low injection pressure. Prolonging the injection time is beneficial to reduce internal stress and prevent shrinkage cavity and deformation.
3. Various types of gates can be used, and the gate is connected with the plastic part in an arc to avoid damage to the plastic part during the gate. The demoulding slope is large, and the ejection is uniform. The wall thickness of the plastic part is uniform, and there are no inserts as much as possible, such as Inserts should be preheated.
To sum up, PS material is an excellent choice for carrier tape raw materials because of its unique properties and formability. As a thermoplastic polymer, PS is economical, rigid and heat resistant. Additionally, its moisture resistance makes it ideal for protecting electronic components during transport and storage.
Understanding PS material properties and their impact on the forming process is critical to optimizing carrier tape production. By selecting premium PS materials, we can produce carrier tapes of good quality and high efficiency, ensuring the success of any electronic device production.
