Heat Stabilizers for PVC: A complete guide-3

Lead-based Stabilizers

Lead-based stabilizers offer the best electrical properties. This is stated by and large by the fact of the insolubility property of lead chlorides formed during stabilization. The Lead-based One Pack Stabilizers have a proportionate combination of Lead Stearate, Dibasic Lead Stearate, and Lubricants that give synergistic effects. The diligently manufactured lead-based stabilizers make processing easy and show excellent properties.

Benefits of Lead-based Stabilizers

-Excellent heat and light stability

-Higher output, reducing the processing cost.

-Superior gloss.

-Exceptional mechanical and electrical properties

-No variation in wall thickness, resulting in lower rejections and wastages.

-Longer life of screw & barrel.

-Consistent physical properties such as impact strength and pressure test.

-Display a wider processing range

Liquid Mixed Metal Stabilizers

The liquid mixed metal stabilizers are based on metal octoates of Ba, Cd, K, Zn for several flexible applications. They provide moderate to high heat stability. Mixed metal stabilizers are more versatile, proprietary & available in many grades.

Benefits of Liquid Mixed Metal Stabilizers

-Barium, Cadmium & Zinc based stabilizers are the most efficient liquid stabilizers and are used in Footwear and Calendaring products.

-Barium & Zinc based liquid stabilizers modern range of non-toxic and are best suited for leather cloth application

-Cadmium & Zinc based liquid stabilizers are used for Foamed leather cloth, Flexible Extrusions, etc.

Organotin stabilizers

Organotin stabilizers are said to be the most efficient and best stabilizers for PVC due to their performance, usage, toxicity and compatibility. organotin stabilizers offer excellent thermal performance even at 0.3 PHR and hence are employed as the most efficient thermal stabilizers. With their outstanding colour retention in plasticized and rigid PVC processing properties, organotin stabilizers find multiple applications.

Benefits of organotin Stabilizers

-Excellent heat stability

-Long-term colour hold

-Works for plasticised as well as unplasticised PVC

-Best for transparent applications

-Good heat stability, transparency and non-yellowing

Heat Stabilizers undeniably play a major part in the PVC industry and hence choosing the best-in-market product is crucial. Hope this article gives an overall understanding of this vast subject.
