What else can I help you with?
What chemical and physical properties of plastic make it a perfect material as substitute to other thing?
Some examples: - plastics have a very low density - plastics are not corroded - platics are easily machined - plastics are non-corrodable
Why is barium sulfate used in plastics?
Barium sulfate is used in plastics as a filler to improve the material's density, stiffness, and flame retardant properties. It also helps to enhance the plastics' resistance to heat and chemicals, making the final product more durable and suitable for various applications.
Is a micrometer larger or smaller than a meter?
Smaller a micrometer is 1/1,000,000 of a meter
What type of plastic are wheelie bins made from?
High density polyethylene, though some bins are made from recycled plastics.
What are the different types of plastics?
Types of plastic - polyethylene (HDPE or LDPE) found in plastic bags and shampoo bottles - polystyrene (PS) found in computer cases - polypropylene (PP) found in dishwasher safe containers - polyethylene terephthalate (PET) found in soda bottles - polyvinyl chloride (PVC) More generally speaking in engineering, plastics are divided into thermoplastic plastics and thermoset plastics These are based on their properties upon reheating after the plastic is molded. Thermoplastic plastics when heated will melt whereas thermoset plastics will not melt but only burn This is due to the way the branches of polymers coordinate. Thermoplastic plastics governed by largely van der waals forces. Thermoset plastics are crosslinked by covalent bonds
What is more accurate in measuring the density of an object the vernier caliper or the micrometer caliper?
The micrometer caliper is generally more accurate in measuring the density of an object compared to the vernier caliper. This is because the micrometer caliper has a higher precision and can measure with greater accuracy, typically up to 0.01mm.
Why would some plastics sink in alcohol?
Because alcohol will not dissolve these type of plastics and their density is more than the density of the alcohol.
What chemical and physical properties of plastic make it a perfect material as substitute to other thing?
Some examples: - plastics have a very low density - plastics are not corroded - platics are easily machined - plastics are non-corrodable
What is a micrometer equal to?
A micrometer is equal to exactly 1 micrometer.
Is plastic a condoctor?
The term plastic has a broad definition as regards materials. There are thousands of plastics. We often think of plastics as organic polymers, and we will generally find that these materials are not good conductors. Different substances added to plastics during production can change this, but we usually find that plastics do not support current flow, and, therefore, might best be considered insulators rather than conductors.
Which is greate a micrometer or decimeter?
micrometer
Which is greater a micrometer or a decimeter?
Micrometer
Who is the inventor of the micrometer?
Richard micrometer.
What makes plastics different from other engineering material metals and plastics?
Plastics are organic materials with low density, having low hardness, they are insulators, they are resistant to many chemicals, they doesn't resist to high temperature, they have poor thermal and electrical conductivity.
What is the abbreviation for micrometer?
The abbreviation for micrometer is µm
What are the advantages micrometer?
"What is the advantages of using micrometer?
How is HDPE manufactured?
High-density polyethylene (HDPE) is one of the most commonly used plastics in the United States
