Polypropylene (PP) Injection Molding in SeaskyMedical

SeaskyMedical is a medical molding company and is known for its Polypropylene molding services. We also allow custom PP molding services depending on the client’s prerequisites. We have professionals for medical product development, material selection, and mold tooling making. We use PP mold to develop plastic hinges, medical equipment closures, medical sampling tube, covid test box,, and several other surgical disposables.

Custom Various Polypropylene (PP)
Molding Services

Undoubtedly, Polypropylene is a strong material with decent enough resistance to wear and tear. There are different types of Polypropylene molding services that we are providing at SeaskyMedical.

Medical Injection Molding

Medical device injection molding is a cost-effective and efficient method of producing medical items, equipment, medical device assembly line models, and autoclavable labware with high levels of precision, accuracy, and quality.

Medical Overmolding

Overmolding is another type of PP injection molding procedure where two or more parts of the same or different designs are clipped jointly. Plastic overmolding is done by utilizing heat and pressure apart from liquid silicone.

Insert Molding

Medical Insert molding is the method of molding or constructing plastic parts close to the plastic parts. With this process, both simple and complicated PP molded components can be inserted.

Medical Micro Molding

Micro molding is a procedure for producing plastics elements for shot weights (1 to 0.1 grams) with 10 to 100 micron tolerance. This helps in the creation of high-quality, better-precision, and micron-tolerance thermoplastic components.

Ultrasonic Bonding

Ultrasonic molding or ultrasonic microinjection molding is one of the latest technologies provided for our clients. This process utilizes high-power ultrasound to soften and mold thermoplastic polymers to generate varieties with mini and micro-features.

What is PP Polypropylene plastic material?

Polypropylene is becoming highly popular in the medical plastic ​injection molding industry. It is a cost-effective polymer that is light in weight and features incredible chemical resistance. At SeaskyMedical, various Polypropylene choices are accessible for injection molding applications. Each of them have their own set of unique quality, reliability, and design standards.

Polypropylene has another name, which is polypropene. It is a thermoplastic polymer utilized in a broad range of applications. This material is used to manufacture medical equipment packaging, food packaging, bottled, containers, and more. It is generated through chain-growth polymerization from the monomer propylene.

What are the PP material properties?

Polypropylene Molding

Polypropylene injection molding is used in several primary and industrial applications, including the medical field, automotive industry, consumer goods, manufacturing furniture, and many more.

Tensile Strength

The tensile strength of Polypropylene material at room temperature is ~4700 psi.

Impact Strength

At room temperature, Polypropylene material features ~0.7 ft-lb/in notched Izod impact strength.

Melting Point

The melting point of Polypropylene material is 130 degrees Celsius.

Chemical Resistance

This material does not deform or deteriorate when in touch with specific chemicals.


Polypropylene material retains a relatively increased resistance to electricity. It is very beneficial for electronic parts.


Polypropylene is a lightweight polymer. Because of its lightweight, it is an ideal choice for various lightweight applications.

Difference between Polypropylene vs Nylon(Polyamide)

Polypropylene and Nylon (polyamide) are both synthetic polymers. Though both of them are quite similar, their differences in individual structures and other crucial distinctions make them different.


Polypropylene is an additional polymer, and it is the result of uniting monomers jointly. Meanwhile, Nylon is a condensation polymer in which moisture molecules are deported when polyamide monomers blend together.

Durability And Strength

Though Polypropylene and Nylon are reliable, Polypropylene is much stronger than Nylon. In addition to that, Polypropylene is often known as "steel of plastics" because of its increased strength.

Heat Resistance

Both PP and PA show resistance to heat. However, Nylon features higher melt viscosity, which makes it much more heat-resistant compared to Polypropylene.

Why We Use Polypropylene PP Material for Plastic Injection Molding

Polypropylene injection molding is utilized in several applications and fields due to its effective physical, chemical, mechanical, and thermal properties. It can be strengthened with glass fiber or minerals to improve the overall mechanical properties.


For injection molding, it is possible to use both Polypropylene and Nylon. PP is easy to use in injection molding services because it comes with a lower melt viscosity.
