Plastic part
* are polyethylene and polypropylene.
* can melt or crack.

### plastic:

Biodegradable plastic
* decompose through the action of bacteria.
* is made by adding starch to the plastic.

### plastic:

Black plastic
* absorbs the light directly and is itself heated.
* can encourage a buildup of vole populations.
* has the potential to burn whatever touches it.
* helps keep the weeds under control and keeps the soil moisturized
  - melons mature faster
* is probably the best known inorganic mulch product.
* is the most commonly used inorganic mulch
  - frequently used inorganic mulch
* poor mulch for landscape plantings.
* provides weed control and is used with several warm-season crops.
* suppresses weeds, but it also limits water infiltration and gas exchange.
* warms the soil, which is an advantage in the spring but can be harmful in the summer.

Cellulosic
* are derived from naturally occuring cellulose through chemical reactions and processing.
* is plastic

Clear plastic
* allows sunlight to penetrate and heat up the logs.
* heats the soil but encourages weed growth.

Common plastic
* Many common plastics are made from hydrocarbon monomers.
* are prime generators of static electricity.

Different plastic
* have different dielectric constants.
* used for wedges have different temperature coefficients.

Engineering plastic
* Most engineering plastics are polymer blends.
* are very strong, and designed to carry heavy loads.

Molten plastic
* causes severe burns.
* is forced under enormous pressure into intricate molds
  - injected under pressure into a closed, split-cavity mould that is cooled

Phone card
* are cards
  - legal tenders
* is plastic

Plastic flow
* can also cause the annihilation of preexisting craters or change surface roughness.
* means that microcracks in the glass become filled in.
* occurs when the deformation occurs at no volume change.

Recycling plastic
* can save finite oil resources.
* leads to energy savings and helps to conserve the earth's oil reserves.
* uses only five to ten percent as much energy as manufacturing new plastic.

Resinoid
* are plastic
  - soluble in high-grade, odorless alcohols
* range from liquids to solids.

Soft plastic
* Some soft plastic is formulated to either sink or float.
* are also a favorite used on jigs and with out.
* present a greater hazard than hard plastics do.

### plastic:

Thermoplastic
* are generally softer and easier to machine than thermosets
  - like wax
  - materials that melt on heating and generally contain little or no crosslinking
  - most often incompatible with highly aromatic LCPs
  - one of the main two types of plastics
* become soft and melt at elevated temperatures
  - viscous on heating and can be extruded in many forms
  - polymers
* lose some of their desirable properties when they are remelted.
* soften and flow when heated and are normally shaped by heat and pressure.
  * and thermoplastic materials have many features. Some products made from thermoplastic materials are used for electronics applications. This way they protect against electrostatic discharge and radio frequency interference. Thermoplastics are one of the main two types of plastics.

### plastic | thermoplastic resin:

Celluloid
* can melt and burn easily, however.
* has certain characteristics which differentiate it from other plastics.
