Plastic gaskets are used in various industries as flat washers or injection gaskets. Discover production techniques and usage areas. Check out our catalogue.
Emerging industrial needs as well as traditional metal or rubber sealsplastic gasketsbrought to the fore. Thanks to its lightness, flexibility and cost advantage, it can be used in many areasplastic based gasketsis preferred.
In this article, “What is a plastic gasket, for what purpose is it used and how is it produced?We will answer your questions and also discuss in detail what it is useful for in which sectors.
What is a Plastic Gasket?
plastic gasketIt is a part that is generally produced from polymer-based materials and performs the functions of sealing, impact absorption or surface protection between two surfaces.
It can be produced in the following types depending on the purpose of use:
- flat plastic stamp: Surface protector or gap compensator in flange, bolt and similar connections.
- injection gasket: Gasket products with complex geometry, shaped with special molds.
- sealing plastic: Parts that perform a sealing function, usually with elastomer additives.
Technical Tasks of Plastic Gaskets
- sealing: It is used to prevent the passage of fluids. It is especially effective in low/medium pressure systems.
- Fill in the Blank: Compensates for micro-openings that occur during assembly.
- Vibration Damping: Reduces mechanical vibrations in machines.
- Surface Protection: Prevents wear on metal surfaces and protects the paint layer.
- Insulation: Provides electrical insulation (for example, in panel gaskets).
What Materials Is It Made From?
The following materials are generally preferred in plastic gasket production:
| Material | Features | APPLICATION |
| PE (Polyethylene) | Lightweight, chemical resistant | Water systems, fittings |
| PP (Polypropylene) | Resistant to heat and solvents | laboratory systems |
| PA (Polyamide – Nylon) | High mechanical strength | automotive parts |
| PTFE (Teflon) | High temperature and chemical resistance | Chemistry and medical applications |
| PVC | Economical, environmentally protected | electrical boxes, panels |

Frequently Asked Questions
Is the plastic gasket sufficient for sealing?
It provides high efficiency in medium-low pressure applications with suitable material and form.
Are plastic gaskets heat resistant?
It depends on the material used. For example, PTFE can withstand up to 260°C.
What is the difference between a gasket produced by injection and a cut gasket?
Injection gaskets can have complex geometries; Cut gaskets are in flat form and low cost.
Can plastic gaskets with special forms be produced?
Yes, special production is carried out with technical drawings or samples.
