Question about: Plastic Canvas Needlepoint?
- Plastic canvas actually comes in four different sizes; five mesh (five holes per inch), seven mesh (seven holes per inch), ten mesh (ten holes per inch), and fourteen mesh (fourteen holes per inch). The seven mesh is the most popular size of plastic canvas used in craft projects. The following yarns and thread work for seven mesh plastic canvas projects; use size 16 needle. worsted weight yarn plastic canvas yarn tapestry yarn - use two strands Persian wool embroidery floss - use six strands for detail extras Here are the yarns and threads which will work on ten mesh plastic canvas projects;use size 20 needle. sport weight yarn tapestry yarn Persian wool pearl cotton embroidery floss - use 12 strandss

what classification of plastic?
- There are two types of plastics: thermoplastics and thermosetting polymers. Thermoplastics are the plastics that do not undergo chemical change in their composition when heated and can be molded again and again. Examples include polyethylene, polypropylene, polystyrene and polyvinyl chloride. Common thermoplastics range from 20,000 to 500,000 amu, while thermosets are assumed to have infinite molecular weight. These chains are made up of many repeating molecular units, known as repeat units, derived from monomers; each polymer chain will have several thousand repeating units. Thermosets can melt and take shape once; after they have solidified, they stay solid. In the thermosetting process, a chemical reaction occurs that is irreversible. The vulcanization of rubber is a thermosetting process. Before heating with sulfur, the polyisoprene is a tacky, slightly runny material, but after vulcanization the product is rigid and non-tacky.s

thermosetting plastics kettle?
- thermosetting plastics can only be formed once from a liquid state, once they have cooled the polymer chains in the plastic form cross links, this in turn prevents the plastic from melting once heated after initial forming and cooling. if you did heat it a lot it would burn, not melt. so using it in a kettle is good because it wont rust, its electrically safe and it wont go soft and floppy when hot.s
