Product Detail

CAS 532-32-1 Sodium Benzoate Carboxylate Nucleating Agent For General Purpose Polypropylene

Product Overview

CAS 532-32-1 Sodium Benzoate is a classic and reliable carboxylate nucleating agent, specially developed for general-purpose polypropylene modification. As a typical alpha crystal nucleator, it can effectively induce stable α-crystal formation in PP materials, refine internal crystal grains and uniformize crystal structure. This product significantly accelerates crystallization speed, increases crystallization temperature and shortens molding cycle, greatly improving the production efficiency of general PP products. It also optimizes the rigidity, hardness and dimensional stability of polypropylene, reducing shrinkage and warpage. With stable performance and high cost performance, it is the most mainstream nucleating additive for conventional general-grade polypropylene processing.

Core Features

Professional Carboxylate Nucleation System: Belongs to classic carboxylate nucleating agent, with stable and mature nucleation mechanism, excellent adaptability to general PP resins.

Excellent General-Purpose PP Modification: Perfectly matching various ordinary polypropylene materials, covering most civilian and industrial general PP modification scenarios.

Efficient Crystallization Optimization: Promote α-crystal growth, speed up cooling and shaping, effectively improve factory continuous production efficiency.

Stabilize Product Dimensions: Uniform crystal structure improves material compactness, reduces product shrinkage, warpage and deformation.

Cost-Effective & Practical: Mature formula, low comprehensive usage cost, stable batch quality, suitable for large-scale industrial mass production.

Product Specifications

Product Name: Sodium Benzoate Carboxylate Nucleating Agent

CAS No: 532-32-1

Chemical Category: Carboxylate Nucleating Agent

Appearance: White Crystalline Powder

Applicable Material: General Purpose Polypropylene (PP)

Crystal Type: Alpha Crystal Nucleator

Recommended Dosage: 0.2%–0.5%

Application Scope

Widely used in all kinds of general-purpose polypropylene modified products. Suitable for PP daily necessities, common injection molding parts, packaging containers, ordinary industrial structural parts, PP extrusion profiles and other general-grade plastic products. It is the preferred additive for conventional PP modification that requires basic nucleation, crystallization acceleration and dimensional stabilization.

Usage Guide

Uniformly dry mix sodium benzoate powder with general-purpose PP resin particles before processing. It can be directly added for one-time mixing production, or made into nucleating masterbatch to obtain more uniform dispersion and better modification effect. Conventional polypropylene injection and extrusion processes are applicable. Adjust the dosage appropriately according to actual product performance requirements and production conditions.

Packaging & Storage

Packaging: 25kg standard moisture-proof packaging bag with inner lining for dust-proof and moisture-proof protection.

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