2. Purpose of This Website
The Website is primarily intended for business customers, engineers, procurement professionals, OEM manufacturers, distributors, and other commercial users.
Website content may include information concerning:
- PTFE and fluoropolymer materials;
- PTFE sheets, rods, tubing, films, and other stock shapes;
- PFA, FEP, PVDF, and related fluoropolymers;
- custom-machined PTFE components;
- manufacturing capabilities;
- technical properties;
- applications;
- quality and compliance information;
- quotation and project inquiries.
Unless expressly stated otherwise, Website content is provided for general informational and preliminary evaluation purposes.
3. Requests for Quotation
The Website allows users to submit quotation requests and project information.
You may provide information including:
- product requirements;
- drawings;
- CAD files;
- dimensions;
- quantities;
- tolerances;
- material requirements;
- application conditions;
- technical specifications;
- delivery requirements.
Submitting a Request for Quote does not by itself create a purchase contract or obligation for either party.
Golden Collar may review the information provided and issue a separate quotation.
A quotation may include additional commercial terms regarding pricing, quantities, tooling, manufacturing, delivery, payment, inspection, documentation, or other project requirements.
4. Quotations and Orders
Quotations issued by Golden Collar are subject to the conditions stated in the applicable quotation.
Prices, lead times, minimum order quantities, material availability, tooling requirements, shipping arrangements, and other commercial conditions may vary depending on the project.
Unless otherwise agreed in writing, a commercial transaction will be governed by the applicable quotation, accepted purchase order, order confirmation, sales agreement, or other written documentation between Golden Collar and the customer.
If a specific written agreement conflicts with these Website Terms, the specific agreement will generally control for that transaction.
If the Website later provides direct online checkout or payment functionality, any specific checkout or purchase terms presented as part of that transaction will also apply together with applicable law.
5. Technical and Product Information
Golden Collar makes reasonable efforts to provide accurate product and technical information.
However, PTFE and other fluoropolymer properties can vary depending on factors including:
- polymer grade;
- filler content;
- manufacturing process;
- dimensions;
- product geometry;
- temperature;
- pressure;
- chemical exposure;
- mechanical load;
- operating environment;
- installation conditions.
Therefore, technical information on the Website should not automatically be treated as a final specification for a particular project.
Final requirements should be confirmed through applicable drawings, specifications, quotations, technical documents, or written agreements.
6. Product Suitability
Customers are responsible for determining whether a material or product is suitable for their intended application.
Information describing common applications in industries such as semiconductor, chemical processing, electronics, automotive, food processing, or medical equipment does not mean that every PTFE or fluoropolymer product is suitable for every application in that industry.
For critical applications, customers should independently confirm relevant requirements such as:
- material grade;
- dimensional tolerances;
- chemical compatibility;
- temperature limits;
- pressure limits;
- mechanical properties;
- purity;
- electrical properties;
- food-contact requirements;
- medical requirements;
- regulatory requirements;
- required certifications or testing.
Where appropriate, customers should perform their own validation, testing, and engineering assessment.
7. Drawings and Uploaded Files
The Website may allow users to upload:
- PDF files;
- STEP or STP files;
- STL files;
- DWG or DXF files;
- images;
- drawings;
- specifications;
- CAD files;
- other technical documents.
By submitting a file, you represent that you have the legal right and authority to provide that file to Golden Collar for quotation, technical evaluation, manufacturing review, or related business purposes.
You remain responsible for the intellectual property contained in files you provide.
Submitting a drawing or technical file does not transfer ownership of your intellectual property to Golden Collar.
Golden Collar may use submitted files only as reasonably necessary to evaluate the inquiry, prepare a quotation, support manufacturing, provide technical assistance, perform quality activities, or maintain appropriate business records.
8. Confidential Information and NDAs
Golden Collar recognizes that customer drawings, specifications, CAD files, and project information may contain commercially sensitive information.
We use reasonable measures intended to protect information submitted to us.
However, simply uploading a file through the Website does not automatically create a separate Non-Disclosure Agreement (NDA).
If your project involves confidential designs, trade secrets, proprietary technology, export-controlled information, or other information requiring contractual confidentiality protections, please arrange an NDA or other appropriate written agreement with Golden Collar before submitting highly sensitive information.
9. Accuracy of Drawings and Customer Information
Customers are responsible for providing accurate and complete information necessary to evaluate or manufacture a project.
This may include:
- dimensions;
- tolerances;
- material specifications;
- quantities;
- drawings;
- revision numbers;
- operating requirements;
- inspection requirements;
- compliance requirements.
Golden Collar is not responsible for problems resulting from materially inaccurate, incomplete, outdated, conflicting, or unauthorized information supplied by the customer.
Where specifications conflict, clarification may be required before production.
10. Certifications and Compliance
References on the Website to certifications, standards, compliance requirements, or material properties are general unless specifically identified as applying to a particular product, material grade, production batch, or project.
