One Pack Stabilizers

What Are One-Pack Stabilizers

One-pack stabilizers are pre-blended additive systems that combine heat stabilizers, lubricants, and functional additives into a single, ready-to-use formulation. Designed to simplify manufacturing processes, they eliminate the need for manufacturers to source, weigh, and blend multiple individual additives separately. By integrating all essential components into a balanced formulation, one-pack stabilizers help improve production efficiency, reduce formulation errors, and ensure consistent product quality from batch to batch. They are widely used in polymer processing industries where reliable thermal stability, smooth processing, and repeatable performance are critical.

At Evergreen Chemical, our premium-grade One-Pack Stabilizers are manufactured under stringent quality control systems with complete back integration and 100% automated production processes. Available in both lead-based and calcium-zinc-based systems, our formulations are tailored to meet the specific processing requirements of a wide range of applications while complying with international standards such as RoHS and REACH.

One-Pack Stabilizers for Plastic Manufacturing

In plastic manufacturing, maintaining consistency throughout production is essential to achieving high-quality finished products. Variations in additive dosage or improper blending can result in unstable processing conditions, increased waste, and inconsistent product performance.

One-pack stabilizers simplify the manufacturing process by providing a ready-to-use solution that incorporates carefully balanced additives into a single package. This reduces formulation complexity and minimizes the risk of human error during material preparation. The pre-optimized composition helps improve processability, enhance thermal stability, and maintain consistent physical properties throughout production. Manufacturers can benefit from improved productivity, lower rejection rates, and more efficient inventory management. For processors seeking operational simplicity and repeatable performance, one-pack stabilizers provide an effective solution that supports both manufacturing efficiency and finished product quality.

One-Pack Stabilizers for PVC Manufacturing

The benefits of one-pack stabilizers are particularly significant in PVC manufacturing, where precise control of thermal stability, lubrication balance, and processing behavior directly impacts product performance. PVC processing involves exposure to elevated temperatures and mechanical stress during extrusion, injection moulding, calendering, and plastisol processing. Without properly balanced additives, manufacturers may encounter degradation, inconsistent fusion, poor surface appearance, unstable wall thickness, and increased scrap rates.

One-pack stabilizers address these challenges by combining heat stabilizers, lubricants, and functional additives in optimized ratios specifically designed for PVC applications. Evergreen offers two primary one-pack stabilizer systems:

Lead-Based One-Pack Stabilizers

Lead-based formulations consist of optimized blends of Lead Stearate, Di-Basic Lead Stearate (DBLS), Tri-Basic Lead Sulphate (TBLS), and high-performance lubricants. These systems provide:

• Synergistic thermal stability and lubrication
• Excellent processing characteristics
• Improved impact strength and pressure resistance
• Reduced rejection rates
• Reliable long-term durability for demanding PVC applications

Calcium-Zinc Based One-Pack Stabilizers

Calcium-zinc formulations represent a modern, environmentally responsible alternative designed to meet increasingly stringent regulatory requirements. Utilizing Hydrotalcite (HDT) to enhance heat stability, these systems offer:

• Heavy-metal-free formulations
• Compliance with RoHS and REACH requirements
• Superior surface gloss
• Consistent wall thickness
• High production output
• Excellent processing efficiency

One-Pack Stabilizers for Other Industries

Although one-pack stabilizers are most commonly associated with PVC processing, their ready-to-use approach offers advantages across other polymer-based industries as well. Applications extend to:

• Plasticized polymer processing requiring simplified additive management
• Flexible product manufacturing with demanding production schedules
• Flooring applications where consistent appearance and dimensional stability are critical
• Consumer and industrial products subject to regulatory compliance requirements
• Manufacturers seeking to streamline production and improve process control

How to Choose the Right One-Pack Stabilizers for Your Application

Choosing the right one-pack stabilizer begins with understanding your production process, application requirements, and regulatory obligations.

A lead-based one-pack stabilizer may be suitable if your application requires:

• Excellent thermal stability under demanding processing conditions
• Strong mechanical performance
• High impact and pressure resistance
• Proven performance in rigid PVC applications

A calcium-zinc one-pack stabilizer may be the preferred choice if you require:

• Heavy-metal-free formulations
• Compliance with RoHS, REACH, and other environmental standards
• Superior surface appearance
• Stable wall thickness and consistent output
• Sustainable alternatives without sacrificing productivity

At Evergreen Chemical, we understand that no two applications are exactly alike. Whether you manufacture rigid PVC pipes, flexible wires and cables, shoe soles, synthetic leather, plastisol products, or specialty PVC compounds, our technical team can recommend a one-pack stabilizer formulation tailored to your specific needs.
