Stay away from heat sources: PVC foaming agents will change their properties when exposed to heat, so they need to be kept away from flames, heat pipes, heaters, or other heat sources.
Safe operation: Adding PVC foaming regulator may generate dust, which may cause harm to the body when in contact with eyes or skin. Therefore, protective measures should be taken during operation.
Reasonable control of dosage: When using PVC foaming regulator, the dosage should be reasonably controlled according to the amount of material. Excessive use of modifiers may lead to poor plastic properties and even prevent molding.
Choosing the appropriate regulator: PVC foam regulators with different properties need to be selected for products of different types and thicknesses. For example, the types of regulators suitable for thin foam boards and thick foam boards are different and need to be selected according to specific needs.
Regular cleaning of equipment: In order to ensure the good performance of the equipment, it is necessary to regularly clean the equipment to extend its usage time and ensure its efficiency.
The role and performance characteristics of PVC foaming regulator
Accelerated plasticization: PVC foam modifiers can accelerate the melting, adhesion, and plasticization of PVC materials, reduce processing temperatures, and increase material fluidity.
Enhancing melt strength: Adjuvants can enhance the strength of PVC melt, making the foaming pores uniform and dense, and improving the mechanical properties of the material.
Optimizing the cell structure: Regulators can regulate the viscoelasticity of PVC melt, ensuring the morphological stability of cell growth and enhancing dimensional stability.
Improving surface quality: Regulators help to evenly disperse other additives, improve the surface quality of foam boards, and make them smoother and more delicate.
