Polyurethane Properties: Tailoring PUR Hard Block Segments

Polyurethanes are a special class of segmented block copolymers, consisting of alternating sequences of soft and hard segments. The soft segment is generally based on polyether or polyester polyols with glass transitions (Tg) well below room temperature, while the hard segment is composed of a diisocyanate and chain extender. The hard segment is often crystalline.

What Is Coil and Can Coating? How Does MPO Play A Role?

Coil and can coating is an organic material that’s applied on rolled metal strip in a continuous process which includes cleaning (if necessary) and chemical pre-treatment of the metal surface.  It also includes either one-sided or two-sided, single or multiple application of (liquid) paints or coating powders, which are subsequently cured and/or laminated with permanent plastic films, cleaning, chemical pretreatment, primer coat application, curing, final coat application, second curing, exit accumulator, and recoilers.

2 Methyl 1, 3 Propanediol (MPO) Uses for Neopentyl Glycol (NPG) Applications

At Gantrade, we offer an array of diols and polyols, a group of  versatile hydroxyl-functional intermediates used in a broad range of applications and industries.

Neopentyl Glycol, NPG (2, 2-dimethylpropane-1, 3-diol) is the standard diol for high performance coating resins. The polyesters synthesized by NPG with saturated or unsaturated di-acids offer a great ingredient for paints, lubricants, plasticizers and fiberglass-reinforced plastics applications. NPG enhances stability toward heat, light, and water.  NPG achieves high performance of resins due to its resistance to oxidation, its non-polar chemical nature, and steric retardation of hydrolysis. Most polyester resin formulations contain NPG as the sole glycol component, or feature NPG in conjunction with a modifying glycol to achieve the desired properties.

MPO Polyester Polyol, Rain or Shine

In polyurethane processing, manufacturers always use polyester polyols as important raw materials, to make prepolymers with isocyanates or as chain extenders or curatives.  Due to the good oxidation and UV resistance, good wear and tear resistance, good heat performance and solvent resistance. Many polyurethane parts feature  polyester polyols to prepare them for the toughest environments and applications.
