Type of Resins Used in the Construction Industry

There are a few different types of resins that are used in the construction industry. These are HDPE, LDPE, LLDPE, and mLLDPE. Understanding the differences between these materials will help you choose the right one for the job.


HDPE Resins are a new generation of polymers that are made to be durable and flexible. These plastics are also recyclable. This makes them ideal for a wide variety of packaging applications. For example, they can be used in stand-up pouches and thermoforming webs.

High density polyethylene (HDPE) resins are polymers made through a polymerization process of ethylene. The process requires a catalyst and takes place at low pressure. This results in a polymer with a long, linear chain and small amounts of comonomers. High density polyethylene resins can be processed in a variety of ways, including blow molding, injection molding, and rotational molding. They are also used in plastic fuel tanks.

The company’s product range extends to a variety of applications including food packaging. High-density polyethylene resins provide extended shelf life and help prevent spoilage. As the food packaging industry continues to expand, HDPE resins will likely continue to enjoy a healthy market.


LDPE Resins for healthcare applications have been produced to comply with applicable USP and EU pharmacopoeia monographs and have achieved the Drug Master File (DMF) number. These resins are highly dense, offer high melt strength, have low MFR and good processing and design flexibility.

LDPE resins are widely used in a wide variety of applications. These include consumer bags, heavy duty sacks, turf bags, mulch films and silage wrap. They are suitable for a range of injection-molded products and are also used for food packaging applications.

LDPE resins are produced by a high pressure autoclave process. They are particularly suitable for blown film extrusion and injection molding. These resins have excellent processability and high optical properties. They can be blended with other PE resins to create various applications.

Another advantage of film coextrusion technology is that producers can use a low density PE resin in combination with a higher density resin. Depending on the resin used, the coextrusion process may involve a two or three-layered film. A three-layer structure is the most common.


Linear low density polyethylene resins, or LLDPEs, are polyethylene resins that exhibit superior physical properties, including good impact and puncture resistance, low stretch and excellent flexibility. These resins are ideal for a wide variety of packaging applications, including grocery bags, produce wraps, dairy cartons, and cereal boxes.

The most common types of LLDPE resins are high density and low density. They are often used in blends with additives or other polymers. If you are interested in learning more about LLDPE, complete the form below. A representative will contact you as soon as possible.

The method of this invention can be used for a variety of materials, including high density and medium density polyethylene. It is also applicable to high molecular-weight low-density polyethylene. By definition, this polymer has a density less than 0.930 g/cm3.


LyondellBasell, the world’s third largest petrochemicals company, recently unveiled its new line of mLLDPE resins, dubbed Starflex. This material promises to deliver lightweight, stronger flexible packaging while providing cost savings for manufacturers. It also has excellent processing properties.

The company estimates that its customers have processed 30 million pounds of mLLDPE resins. It also plans to explore the application of mLLDPE resins for mono and multilayer films. The company is currently manufacturing mLLDPE resins at a Texas facility but plans to expand its production to other plants around the world.

Linear low density polyethylene (LLDPE) resins are ideal for applications requiring flexibility, toughness, and puncture resistance. These materials can be used in consumer and industrial packaging. They are slick, ductile, and have excellent optical properties.

The metallocene catalyzed polymerization process produces extremely pure and consistent resins. It allows resin manufacturers to customize the properties of PE films to meet their specifications. These resins can have low or high melting points and excellent heat resistance. In addition, they have several derivatives that are active catalysts for olefin polymerization.


EVOH Resins are a versatile thermoplastic resin that exhibits superior barrier properties against gases. They are ideal for use in extruded articles and laminated gas barrier packaging films. The high barrier properties of EVOH allow them to be used in various packaging applications including perishable food packaging. However, the material’s barrier properties will diminish when exposed to moisture. Fortunately, this polymer can be co-extruded with protective polypropylene to achieve useful film properties for applications that require gas and moisture barriers.

The first step to using EVOH resin in the production of polymer coatings is to ensure that the resin does not contain excessive moisture. EVOH should be dried to a moisture content of at least 0.4%. This can be accomplished with the use of a desiccant-type circulating air dryer at 90-110 degrees C. This method requires a certain amount of time for the resin to dry completely. EVOH resin should not be over-dried as this can lead to thermal degradation.

EVOH Resins are typically nonbiodegradable. However, with copolymerization and blending, EVOH films can be made biodegradable. However, EVOH films are difficult to recycle. The oxygen barrier layer between the PE layers can become gummed up during reprocessing, leading to holes in the recycled film. On the plus side, EVOH waste does not produce any toxic byproducts if incinerated. Moreover, EVOH resins can be used in a variety of packaging applications, including medical, pharmaceutical, and food packaging.


NYLON type of resins are a versatile material used for various applications. They have high tensile strength, high chemical resistance and low moisture absorption. In addition to this, these polymers are less expensive compared to other nylon grades. Additionally, they can be purchased in various forms, including heat stabilized, flame retardant, glass beaded, and carbon fiber. These materials are also known for their good lubricity and wear resistance.

NYLON type of resins are made from polyamide (also known as nylon). They are very versatile and can be blended with various additives to achieve specific properties. In addition to that, these materials can be easily melt-processed into shapes, fibers, and films. NYLON polymers have become popular over the past few years and are used in a wide range of products.


PPA Resins are a cost-effective alternative to fully aromatic aramids and are used in many industries. They exhibit good heat, oil and solvent resistance. This versatile polyamide can also be used to replace die cast aluminum and zinc. However, it is more difficult to process and can be more expensive than conventional aliphatic amides.

Amodel(r) PPA resins feature fiber reinforcements, heat stabilizers, impact modifiers, flame retardants and other additives. They also come in a variety of processing options. As part of their research, the GK Concept team studied a variety of PPA resins to understand their characteristics.
