Is HDPE same as Delrin?
While HDPE Sheet and Acetal Sheet look similar, they perform quite a bit differently. Acetal is commonly known as: Delrin Homopolymer Acetal, Tecaform AH,Ensital, Unital, Pomalux, Ultraform and many more. HDPE is also known as: Ultraethylux, Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.
What is the density of Delrin?
1.41 g/cm³
Polyoxymethylene/Density
How dense is HDPE plastic?
The density of HDPE can range from 0.93 to 0.97 g, although the density of HDPE is only marginally higher than LDPE (low-density polyethylene).
Is HDPE the same as UHMW?
HDPE (high density polyethylene) is a durable, versatile, low-cost, abrasion- and chemical-resistant plastic material. UHMW (ultra high molecular weight polyethylene) is an extremely tough, abrasion-resistant, low-cost plastic, used for a wide range of wear applications.
Is Delrin stronger than UHMW?
UHMW has surface and chemical properties that are rare to find in high-performance polymers. It is very resistant to most chemicals, UV radiation, and micro-organisms, but doesn’t have the same creep resistance as Delrin.
What material is Delrin?
Delrin® is a crystalline plastic that offers an excellent balance of properties that bridge the gap between metals and plastics. Delrin® possesses high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption. It is chemically resistant to hydrocarbons, solvents and neutral chemicals.
What is the density of carbon fiber?
1.93 g/cm3
The density of the current commercial PAN-based carbon fibers is in the range of 1.75–1.93 g/cm3 [1]. As compared to metals and ceramics used in structural applications, carbon fiber composites have much higher specific strength and modulus.
What is HDPE most commonly used for?
The Top Uses for HDPE Include
- Shampoo Bottles.
- Toys.
- Chemical Containers.
- Pipe Systems.
- Milk Jugs.
- Recycling Bins.
- Grocery Bags.
- Cereal Box Liners.
Is HDPE hard or soft plastic?
As a soft plastic HDPE is found in freezer bags, plastic bags, and other plastic food packaging. You might even find your reusable shopping bags are made from HDPE.
Which plastic has the highest density?
high-density polyethylene
HDPE (high-density polyethylene): HDPE is known for its large strength-to-density ratio. The density of HDPE can range from 0.93 to 0.97 g/cm3 or 970 kg/m3.
What is melt density?
The ratio of the two values—the MFR divided by the MVR—is a measure of the melt density of the material in g/cm³. For example, unfilled and unpigmented polycarbonate has a solid-state density of 1.20 g/cm³ while the melt density of the material is 1.08 g/cm³, or 90% of the solid state density.
