Melon is OEM ventilator diaphragm valve ISO 13485 certified manufacturer, professional experience and free samples for quality reference
2th, Sep received RFQ - Quotation Request Fabric reinforced diaphragm for Valve
below is the Juan' Request of FKM diaphragm :
Description: Fabric reinforced diaphragm that needs to withstand oxygen gas. We are thinking of FKM with fabric reinforcement to improved durability.
Material: Fabric with rubber-coated fabric (oxygen resistant) .
Thickness: 0.45mm nominal
Max Working Pressure: 30 psi
Max Working Temperature: 45 C
Max Axial displacement: 1mm
My first reaction: this is a customized case, different from general accessories
As one rubber & Plastic development specialist, My value is to help customers maximize the value
so before making a quotation, I firstly contact Juan online and know more information about why they choose the FKM membrane.
Juan Reply:
We chose FKM because we commonly see this material in valve diaphragms and we think it might have better mechanical resistance to cyclic movement and 30psi pressure.
We need fabric-reinforced material to improve durability.
and this project is in the development stage.
Anna Reply:
Many different membrane types available in the market today
FKM diaphragm, silicone diaphragm, which is the right one in the ventilator valve with fabric reinforcement to improved durability and withstands oxygen gas.
I replied from the following aspects for client reference
First industry requirements
Ventilator, a medical accessory, must meet FDA, and the material must meet ISO10093
At this point, liquid silicone and silicone diaphragm could meet.
Material properties
if there is not a vibration frequency requirement. It only requires oxygen resistance and fabric reinforcement to improved durability.
Compared with the silicone diaphragm, the FKM diaphragm has no advantages.
Because of silica gel, its tear resistance and oxygen resistance are very good.
And FKM, its performance advantages are mainly strong acid resistance, various oil resistance, weather resistance, etc.
Mould aspect:
In the testing phase, open a compression trial mold is more economic
trial mold is the lowest cost, the shortest time to complete the collection of raw data such as product structure testing,
assembly testing, and potential problems
Sample
FKM and silicone samples, both for testing
client chose FKM because they commonly see this material in valve diaphragms and we think it might have better mechanical resistance to cyclic movement and 30psi pressure.
A variety of sample options, using actual data to let customers understand that we recommend from a practical and professional perspective
Juan, as buyer feedback:
Anna, Melon is one the awesome supplier, we follow your suggestion
formal FKM & Silicone & liquid silicone Membrane quotation is sent to Juan in 24 hour
Now I am waiting for the official order from JUAN. hopefully, negotiations should be successful! but at the technical level, our basic data collection has been completed,
And we are an ISO13485 certified OEM manufacturer. We have developed many different ventilator accessories and accumulated rich experience.
