Product Description
Heat Exchanege Gasket AC190,AC230,AP20,AP25,AP35 Hydrogenated Nitrile Gaskets
Heat Exchanger Gasket:
Formulation: The production begins with the formulation of HNBR compound, which involves blending hydrogenated nitrile butadiene rubber with various additives. These additives can include curing agents, fillers, plasticizers, and antioxidants to achieve the desired performance characteristics.
Mixing: The compounded materials are thoroughly mixed in a controlled environment to ensure uniform distribution of additives and consistent quality.
Extrusion or Molding: The mixed HNBR compound is then processed either through extrusion or molding techniques. Extrusion involves forcing the compound through a die to produce continuous lengths of gasket material with a cross-sectional shape. Molding is used to create gaskets of specific shapes and sizes by injecting the compound into molds under heat and pressure.
Curing: The shaped HNBR gaskets are cured in a heated press or oven to cross-link the polymer chains, thereby imparting the final mechanical and chemical properties.
Finishing: Post-curing, the gaskets may undergo finishing processes such as cutting, trimming, or surface treatments to meet dimensional tolerances and application requirements.

Installation method
Plate heat exchanger sealing gaskets can be divided into 3 forms according to the installation method on the heat exchange plates:
1. Direct sticking type: After applying sealant on the sealing gasket, it is directly glued into the installation groove of the heat exchange plate.
2. Plastic nail inlaid type: The heat exchange plate is designed with assembly holes, and rubber nails are designed on the side of the sealing gasket. After the sealing gasket is placed in the installation slot, the rubber nails are embedded in the assembly holes.
3. Snap-on type: There are buckles on the side of the sealing gasket, and the buckles are used to buckle the sealing gasket onto the heat exchange plate.
The sealing gasket uses different types of rubber according to different media and operating temperatures.

The steps for replacing the gasket in a heating exchanger are as follows:
Q&A
Q1: Does the gaskets product come with a warranty?
A1: Gasket are consumable accessories, and the replacement cycle is generally determined according to the specific conditions of use by the customer. It is related to the use environment, medium, temperature, etc. Usually we recommend purchasing more for replacement and backup purposes.
Q2: Is there a discount available for wholesale or bulk purchases?
Answer: Yes, we offer discounts for wholesale and bulk purchases. If you are interested in purchasing a large quantity of items or engaging in wholesale business, please contact our wholesale department or customer service team for information regarding wholesale discounts and minimum purchase quantities.
