Let’s Boost Your Product

At MCPU Polymer Engineering, we don’t just sell polyurethane ingredients — we solve formulation challenges. Whether you’re trying to eliminate restricted chemicals, improve fire or moisture resistance, boost insulation performance, or increase the sustainability of your products, we partner with you to design high-performance solutions without compromise. Explore the real-world problems we help solve below and discover how our chemistries unlock better outcomes across industries and applications.

Fire Resistance

Improve the FIRE RESISTANCE of most PIR Foams by replacing TCPP, TEP or TOP additives without sacrificing performance.

We think that you don’t need to compromise the properties of your PIR Foams to make them flame retardant. You know that the addition of TCPP alternatives (like TEP) degrades compressive strength.

You will be able to offer a better solution to your customers. Not having to add FR agents saves the customer money because it prevents them from having to revamp their formula when one of these FR agents is banned.

Our Value

Improve the R-Value at low temperature of most PIR Foams, as a result of adding HoneyBee.

R-value can be improved over temperature without adding adulterant such as glass wool.

We believe that adding glass wool or another adulterant is unnecessary if you have an additive that can give you the same K-factor without adulterants. This also gives you an edge-up on the competition and sells more material.

You can save money avoiding the unnecessary use of glass wood and provide a more efficient product to the end user.

Replace traditional high VOC catalysts in Spray Foams.

Adding Yellow Jacket additives into a Spray formula at ~20% level can lessen or even alleviate the need for traditional volatile amine catalysts.

  • Fairly easy to use and incorporate
  • Cost effective
  • Has a performance advantage that other solutions do not have (in addition to K-factor). This could be a decrease in friability or an increase in compressive strength, and/or desirable cell structure.

Lowering of Tg and a tunable Tg range with Yellow Jacket in Visco Foams.

The Tg and Tg range of flexible foam is something that is hard to control with industry standard polyols and additives. Typically, multiple additives are needed to gain the desired effect on one property, let alone several.

By using Yellow Jacket additives at an appropriate level to enhance the properties of flex foam formulations.

Fire Resistance Without Sacrificing Performance

Challenge:

Achieving fire retardancy often compromises key physical properties like tensile strength, elongation, or reactivity — particularly when using additive flame retardants.

Our Solution:

MCPU’s reactive flame retardant technologies chemically bond into the polymer backbone, delivering superior fire resistance without degrading mechanical or processing performance. These solutions are ideal for insulation, construction panels, coatings, and sealants requiring high flame resistance and structural integrity.

Eliminate TCPP from Foam Formulations

Challenge:

TCPP (tris(1-chloro-2-propyl) phosphate) is widely used but increasingly restricted due to environmental and health concerns. Removing it often disrupts foam stability, flame performance, or cell structure.

Our Solution:

Our TCPP-free solutions use reactive chemistry to deliver comparable flame retardancy while enhancing foam integrity, stability, and long-term performance. They are fully compatible with common polyurethane systems and support compliance with current and emerging regulatory standards (e.g., CARB, EPA, REACH).

Energy, Sound, or Vibration Absorption

Challenge:

Standard polyurethane systems often transmit vibration or impact energy rather than dissipating it, resulting in user discomfort or material failure.

Our Solution:

MCPU elastomer systems are engineered for energy damping and noise control in dynamic environments. Whether in footwear, heavy equipment, flooring underlays, or vibration mounts, we balance viscoelastic response, rebound, and durability to help reduce noise, protect users, and extend product life.

Energy Absorption 3 Reasons To Believe

Improve R-Value in Insulation Foams

Challenge:

Low R-value and poor insulation performance stem from suboptimal foam structures and cell collapse over time.

Our Solution:

MCPU polyols and additives are designed to improve foam cell uniformity, reduce gas diffusion, and enhance thermal insulation properties. Our materials help formulators meet or exceed demanding building code R-value targets, particularly in spray polyurethane foam (SPF), panel, and appliance insulation applications.

Add Sustainability Without Losing Performance

Challenge:

Many renewable polyols sacrifice reactivity, stability, or physical properties compared to petrochemical-based alternatives.

Our Solution:

MCPU’s Honey Bee® and Yellow Jacket® soy-based polyols are engineered to provide high-functionality, excellent reactivity, and physical performance comparable to traditional systems — all while increasing bio-based content. They are ideal for formulators seeking LEED credits, USDA BioPreferred status, or low-carbon product development.

Improve Hydrophobicity / Moisture Resistance

Challenge:

Moisture ingress degrades mechanical performance, causes swelling, and shortens the life of polyurethane materials in sealants, coatings, and elastomers.

Our Solution:

We develop polyurethanes with high water resistance, low moisture vapor transmission rates, and excellent dimensional stability. These formulations are tailored for infrastructure, wastewater, marine, and construction applications where moisture exposure is a critical performance factor.

Remove VOCs from Spray Foam Systems

Challenge:

Traditional polyurethane spray systems emit volatile organic compounds (VOCs) that affect indoor air quality and regulatory compliance.

Our Solution:

MCPU offers low- and zero-VOC polyols and modifiers that maintain sprayability and foam performance while significantly reducing emissions. Our solutions help customers meet indoor air standards (e.g., GREENGUARD, California 01350) and improve user safety in residential and commercial insulation.

Improve Glass Transition Temperature (Tg) Without Brittleness

Challenge:

Raising Tg often increases brittleness or reduces elongation, making materials less viable for demanding environments.

Our Solution:

MCPU designs prepolymers and polyol blends that elevate Tg while retaining toughness and elasticity. These materials are ideal for applications requiring thermal stability, such as high-temperature gaskets, adhesives, and performance coatings.

Improve Tear Resistance Without Hurting Tensile Strength

Challenge:

Improving tear resistance typically compromises tensile strength or elongation at break, especially in elastomer systems.

Our Solution:

Our elastomer technologies strike the right balance by reinforcing polymer matrices at the molecular level. The result is enhanced tear strength without brittleness — ideal for footwear, belts, rollers, and other high-stress applications.
