What is Hlmi in plastic?

High Load Melt Index (flow characteristics of molten plastics determination)

What is HMW material?

High Molecular Weight (HMW) High Density Polyethylene (HDPE) resins with very low melt indices (MI2 ranging from 0.03 to 0.1 dg/min) and very broad, multi-modal molecular weight distributions provide high melt strength and excellent impact properties.

What is fractional melt?

A low melt index ( under 1 ) is referred to as a fractional melt or less than a gram / 10 minutes. Lower MI resins are used for pipe and profile extrusion. It’s common sense that resins with high viscosity (resistance to flow) are inherently strong.

What is high load melt index?

For polypropylene, the temperature is 230 C, and for some polyethylenes the load is increased to 21.6 kg, which is called the High Load Melt Index, or HLMI. This is typically used for very low-flow materials, to reduce the test error and get more manageable numbers.

What is the melt flow index of polyethylene?

Melt flow rate is very commonly used for polyolefins, polyethylene being measured at 190 °C and polypropylene at 230 °C.

What is VHMW plastic?

King Hy-Pact® (VHMW) is the super tough industrial polymer sheet that is environmentally stabilized with excellent physical properties.

What is FRAC melt resin?

Natural HDPE Pellets (Frac Melt): Natural High Density Polyethylene Pellets are recycled plastic pellets commonly used in film, bags, pipe, plastic lumber, furniture, pipe, profiles, thermoformed packaging, and more.

What is HDPE frac melt?

High Density Polyethylene (HDPE Plastics) Fractional Melt GAR Plastics is a reliable supplier of high-quality High Density Polyethylene (HDPE Plastics). Our capabilities within our state-of-the-art facility include washing, shredding, grinding, and pelletizing this material.

What is the MFI of pet?

The MFI of PET samples can be determined using the method ASTM D 1238 Standard test method for flow rates of thermoplastics by extrusion plastometer [16]. Melt Indexer Dynisco–Kayeness Polymer Test Systems model LMI 4004 instrument with a heating chamber set at 285°C is used for the PET melting timings.

What is MFI test?

Melt flow index (MFI) is a measure for the ease of flow of melted plastics. Its usage is based on the plastic industry for quality control of thermoplastics. A sample of 5 grams is heated above its melting point and is allowed to flow through a capillary using a piston operated by a specified weight of 5 kg.
