Definitions

• Thermoplastics have been made separately with antistatic and flame retardant properties. This inven ⁇ tion combines both properties into one thermoplastic and the method for preparing the thermoplastic.
• the flame retardants and antistatic compounds are known in the art. There has been difficulty in combining the two into one thermoplastic compound.
• thermoplastic of this invention can be used in a variety of ways.
• sheeting can be made for temporary wall structures and floor insulation in the nuclear industry.
• the sheeting can also be used in the computer maintenance area to drape and floor work surfaces.
• the flame retardant and antista ⁇ tic thermoplastic is well suited for packaging and shipping needs.
• the thermoplastic can be used in a sheet for wrapping and as filler to protect equipment sensitive to an electronic charge.
• the flame retardant qualities are additional protection from hazards to the contents of wrapped or filled packaging.
• Another application is for thermoplastic coating of wires or pipe to be protected from electronic charges and fire damage.
• the thermoplastic can be used in many applica ⁇ tions and it is not intended to define the uses by this description but to give useful examples of the inven ⁇ tion.
• the thermoplastic of this invention is made of conventional thermoplastic resins which are dried at 165°F to 250°F with or without a desiccant so that they contain about 0.1% or less water.
• the antistatic agent is a nontoxic amide which is typically contained in a thermoplastic resin for mixing purposes.
• the flame retardant is similarly contained in a resin for mixing purposes and is an antimony oxide and organic halogen.
• the composition also contains an effective amount of hindered phenol and phosphite stabilizer package or bisphenol polyphenol antioxidants.
• the other ingredients are effective amounts of flame retardant, antistatic agent and antioxidant.
• These additives are commercially available in resins.
• the resin containing the additive promotes uniform mixing with the thermoplastic.
• the flame retardant, antistatic agent and antioxidant are dried as described above for the thermoplastic. All the ingredients contain 0.1% or less water prior to mixing.
• the antistatic compound is a nontoxic amide.
• the commercially available additive is 5% nontoxic amide in a low density polyethylene manufactured as Statcease CD by Techmer Corporation.
• the Statcease product with 5% active ingredient can be used in a 5% to 65% range in the composition of this invention.
