Plastic product manufactures come in not just products for the home but in a plant as well. They make products from liquid resin that is reinforced with fiberglass. Fiber-reinforced plastic products have a lot of uses in the industry, transportation, home, and recreation. Industrial uses are storage tanks, electrical equipment, ducting, pipes, machine components, and corrosion resistant equipment. Some of these plastic product manufactures will spray it on a mold while others use hand lay up. The hand lay-up is a lot stronger and will last longer. Another use for plastics are material made for household use. Plastic manufactures for the home make just about everything. Plastic is put in airbags, and cell phones.
