About Our Products
Heat stabilizers are used in the manufacture of products from PVC (vinyl, polyvinyl chloride). PVC can undergo some degradation at the elevated temperatures used for processing. Heat stabilizers prevent this degradation and allow PVC to be easily and safely processed into many valuable consumer items. In addition, the use of stabilizers extends the useful life of the finished product.
The tin stabilizers are a family of products based on methyl, butyl, and octyl tin materials that are widely used in many PVC applications. They have a long history of good performance, and several have been approved by agencies around the world for critical applications, such as packaging applications with direct food contact and materials used in the distribution of potable water. These approvals are based on extensive testing and evaluation that found these products meet the stringent requirements of the regulations controlling these end uses. The exact type of tin stabilizer used will depend on the application, as cost and performance requirements will vary.
Tin stabilizers offer a number of product benefits and performance characteristics, including:
-
Excellent cost performance
-
Ease of processing, allowing for higher output in extruded applications
-
Color control and color hold, i.e., whiter products that keep their color
-
Outstanding transparency/clarity
-
Resistance to weather in outdoor applications
-
Overall value to the customer
Tin stabilizers have been safely used for more than 40 years in many vinyl applications, including:
-
Building and construction products: Vinyl siding; PVC pipe (drain waste and vent, and potable water); window profiles; fencing, decking and railing; flooring; and wallcoverings.
-
Packaging: Clear food and drink containers, food wrap, blister packaging for pharmaceuticals, and thermoformed packaging
-
Inflatables: swimming pools, floats, water wings, inner tubes, beach balls, air mattresses
-
Household items and miscellaneous: tote bags, shower curtains, toys, sports logos on clothing and apparel
Tin stabilizers can be formulated to meet the specific needs of individual
applications. For example, in some cases it is important to achieve
early color hold, whereas in other products long-term stability under
processing is critical. Different processing techniques and equipment
also may need to be addressed. Tin stabilizers are available for all
types of plastic processing, including extrusion, calendering, injection
molding, blow molding and thermoforming. Additionally, tin stabilizers
can be used in a wide range of formulations, including those with high
filler levels, wood flour compounds, color concentrates, and CPVC.
