CAS 15402-75-2 Calcium Pimelate is an efficient beta nucleator for polypropylene. It induces the formation of β crystal structure inside PP, optimizes internal stress distribution of materials and significantly enhances anti stress crack performance. It effectively prevents crack propagation under long-term stress load, widely used for PP products requiring excellent environmental stress cracking resistance.

Product Detail

CAS 15402-75-2 Calcium Pimelate Nucleator Polypropylene Anti Stress Crack Additive

Product Overview

CAS 15402-75-2 Calcium Pimelate is a high-efficiency beta nucleating agent tailored for polypropylene anti-stress crack modification. Different from conventional rigid nucleators, this product can stably induce PP to form uniform and dense β crystal structure, effectively optimize the internal crystal arrangement and stress distribution of polypropylene materials. It greatly improves the environmental stress cracking resistance of PP products, solves common quality problems such as micro-cracks, crack propagation and premature aging failure caused by long-term mechanical stress and environmental erosion. With stable modification performance and excellent compatibility, it is a professional functional additive for long-service-life polypropylene products.

Core Features

Excellent Anti-Stress Crack Performance: Optimize internal material stress balance, effectively inhibit crack initiation and expansion under long-term static and dynamic stress, greatly improve product durability.

Efficient Beta Crystal Induction: Increase β crystal content in PP matrix, improve material flexibility and stress dispersion ability, fundamentally enhance structural toughness.

Improve Environmental Aging Resistance: Reduce the sensitivity of PP to temperature changes and environmental erosion, avoid stress cracking caused by aging, and extend product service life.

Stable Processing Compatibility: Fine powder with good dispersion, perfectly compatible with PP resin. No precipitation, no odor and stable performance during high-temperature injection and extrusion processing.

Long-Term Stable Modification Effect: The optimized crystal structure can maintain stable mechanical properties for a long time, avoiding performance attenuation in complex service environments.

Product Specifications

Product Name: Calcium Pimelate Beta Nucleating Agent

CAS No: 15402-75-2

Chemical Type: Aliphatic Dicarboxylate Beta Nucleator

Appearance: White Fine Powder

Core Function: Anti Stress Crack, Toughness Improvement, Aging Resistance

Applicable Material: General Polypropylene (PP)

Recommended Dosage: 0.15%–0.4%

Application Scope

Widely used in polypropylene products that require long-term stress resistance and crack resistance. Suitable for PP pressure-bearing pipes, structural injection parts, automotive functional components, outdoor PP profiles, chemical corrosion-resistant containers and other products. It is especially suitable for PP products working in complex environments and prone to stress cracking failure.

Usage Guide

Dry mix Calcium Pimelate powder evenly with PP resin particles before processing. It can be directly added for conventional injection and extrusion production. For higher anti-stress crack stability, it is recommended to prepare beta nucleating masterbatch through twin-screw granulation to achieve more uniform dispersion. Adjust the dosage appropriately according to product stress resistance standards and actual molding processes.

Packaging & Storage

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

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