Product Features & Specifications
Material: It is composed of a mixture of polyolefins and paraffin waxes, which is non-toxic and free from plasticizers.
Flexibility: The film is highly flexible and can be stretched by over 200% of its original length, allowing it to cling and seal around irregular shapes and surfaces effectively.
Resistance: Parafilm M offers good resistance to many polar substances, including inorganic acids, alkaline solutions, and saline solutions, for up to 48 hours. It is not recommended for use with non-polar organic solvents like acetone, diethyl ether, or tetrachloride.
Permeability: It provides a waterproof barrier while remaining gas-permeable, which is ideal for microbiology and cell culture applications as it does not affect oxygen or carbon dioxide permeability.
Temperature Range: The film can withstand temperatures ranging from -45°C to 50°C. Its softening point is at 54°C, and the melting point is at 100°C.
