Polyvinylidene Chloride (PVDC), with the CAS number 9002 - 85 - 1, is a high - performance polymer. It is a thermoplastic resin known for its excellent barrier properties against oxygen, moisture, and odors. The high - quality PVDC offered here comes in various forms such as pellets or powders, which can be customized according to different production requirements.
Some of the key physical properties include a density typically ranging from 1.65 - 1.75 g/cm³. It has a relatively high melting point, usually between 160 - 190°C, which allows it to maintain its integrity under certain high - temperature conditions. PVDC also has good mechanical strength, with a tensile strength that can reach several tens of MPa depending on the formulation and processing methods.
PVDC has a wide range of applications across multiple industries. In the food packaging industry, it is the material of choice for packaging perishable foods. Its excellent oxygen and moisture barrier properties can effectively extend the shelf life of food products, keeping them fresh and preventing spoilage. For example, it is used in the packaging of meats, cheeses, and snacks.
In the pharmaceutical industry, PVDC is used for blister packaging of tablets and capsules. It provides a protective layer that shields the drugs from environmental factors such as humidity and oxygen, ensuring the stability and efficacy of the medications. Additionally, PVDC is also used in the packaging of some high - value chemicals and electronic components, where protection from moisture and contaminants is crucial.
When using PVDC, proper handling is essential. If it is in pellet form, it can be processed through common plastic processing methods such as extrusion, injection molding, or blow molding. Before processing, the pellets should be dried in a dehumidifying dryer to remove any moisture, as moisture can cause defects in the final product.
During the processing, the temperature settings are critical. The processing temperature should be carefully controlled within the recommended range to ensure good flowability and avoid thermal degradation of the PVDC. After processing, the products should be cooled and inspected for any visible defects such as cracks or uneven surfaces.
Case 1: A large - scale meat processing company switched from traditional packaging materials to PVDC - based packaging for its fresh meat products. The oxygen barrier property of PVDC significantly reduced the oxidation of the meat, which led to a 30% increase in the shelf life of the products. This not only reduced the waste of unsold products but also improved customer satisfaction due to the fresher appearance and taste of the meat.
Case 2: A pharmaceutical manufacturer adopted PVDC blister packaging for a new line of anti - allergy tablets. The moisture - proof feature of PVDC ensured that the tablets maintained their chemical stability throughout the storage and transportation process. As a result, the number of product returns due to moisture - related degradation decreased by 40%, saving the company a substantial amount of money.
