Product Detail

CAS 532-32-1 Sodium Benzoate Nucleating Agent Plastic Processing Aid For PP Containers

Product Overview

CAS 532-32-1 Sodium Benzoate is a professional plastic processing aid and alpha nucleating agent specially optimized for PP container production. Tailored for polypropylene packaging and storage container molding processes, this product effectively accelerates material crystallization rate, raises crystallization temperature and greatly shortens molding cycle. It perfectly solves common problems of PP containers such as uneven shrinkage, wall deformation and poor dimensional consistency. Meanwhile, it improves the rigidity, hardness and surface flatness of PP container products, stabilizing product quality for mass production. With excellent processing adaptability and high cost performance, it is a dedicated and reliable additive for PP container manufacturing factories.

Core Features

Specialized for PP Container Molding: Customized formula for PP packaging containers, storage boxes and plastic vessel products, with targeted modification effect.

Improve Processing Efficiency Greatly: Speed up crystallization and cooling shaping, shorten production cycle, effectively increase daily output of PP container products.

Stabilize Container Dimensional Accuracy: Refine crystal grains and uniformize internal structure, reduce shrinkage, warpage and deformation of container walls.

Optimize Product Surface & Hardness: Improve surface smoothness of PP containers, enhance overall rigidity and pressure resistance, upgrade product grade.

Excellent Processing Compatibility: Good miscibility with PP resin, stable performance during high-temperature injection and extrusion, no precipitation, no odor, safe for daily plastic products.

Product Specifications

Product Name: Sodium Benzoate Nucleating Processing Aid

CAS No: 532-32-1

Chemical Type: Carboxylate Alpha Nucleating Agent

Appearance: White Crystalline Powder

Application: Special Processing Aid for PP Containers

Applicable Process: PP Injection & Extrusion Molding

Recommended Dosage: 0.2%–0.5%

Application Scope

Mainly applicable to all kinds of polypropylene container products, including PP food packaging containers, plastic storage boxes, daily use PP vessels, industrial packaging containers and other PP hollow molded products. It is widely used in mass production scenarios that require stable molding size, smooth surface and high production efficiency for PP containers.

Usage Guide

Mix sodium benzoate powder evenly with PP resin particles through dry mixing before molding processing. It can be directly added for conventional PP container injection molding production, or made into nucleating masterbatch to achieve more uniform dispersion and better modification effect. Adjust the dosage appropriately according to container wall thickness, molding process and product quality requirements.

Packaging & Storage

Packaging: 25kg standard industrial moisture-proof bag with inner PE lining, dust-proof and moisture-proof for bulk transportation.

Storage: Store in dry, cool and ventilated warehouse. Keep tightly sealed to prevent moisture absorption and caking. Avoid long-term high temperature and direct sunlight. The shelf life is 24 months under standard storage conditions.
