MODIFIED PTFE MEMBRANES AND DIAPHRAGMS

Being critical components in pumps and hydraulic devices, membranes and diaphragms are produced by different technologies and processes with a range of PTFE grades.
Over the past few years, Guarniflon has been developing, thanks also to its R&D Dept., a process thanks to which the membranes are perfectly shaped one by one according to customers’ technical requirements, starting from Guarniflon semifinished products. The modified PTFE (Guarniflon internal code G500) appears to be the preferred grade thanks to its chemical and mechanical properties, offering an unmatchable elongation at break among the available PTFE materials.
A double advantage for Guarniflon customers: sourcing ready-to-use membranes/diaphragms with unlimited availability of modified PTFE raw materials.

PRIVACY

VENDOR PRIVACY POLICY
Pursuant to Legislative Decree no. 196/2003, and EU Regulation no. 679/2016 (GDPR), and with respect to your personal information subject to processing, we take this opportunity to provide you the following information.

DATA-PROCESSING PURPOSES
Guarniflon S.p.A. a company with registered office on Via T. Tasso No. 12 – 24060 Castelli Calepio (BG) –, Tax ID and VAT No. 01406020162, appearing herein as Data Controller, shall process vendor data for the following purposes:
a) Vetting (financial position, economic and organisational capacity, references, professional qualifications, withholding compliance, insurance coverage, conflicts of interest, anti-corruption and anti-money-laundering compliance, potential reputational impact of the relationship);
b) Vendor contract management;
a) Compliance with applicable law, regulation, or EU statute, or any order issued by any authority mandated by statute, or by any supervisory or control body.

LEGAL BASIS FOR THE DATA PROCESSING
Please note your personal data shall be processed in the following situations, and pursuant to the following legal bases:
a) Processing is necessary to perform under a contract to which you are privy, or for the carrying out of any pre-contractual measures implemented at your request;
b) Processing is necessary to discharge a legal duty incumbent on the Data Controller;
c) Processing is necessary for Data Controller to pursue a legitimate interest; legitimate interests shall include:
   - The interest in executing, managing, and performing those contracts identified in subsection 1(b) hereof;
   - The interest to protect any rights arising - be it directly or indirectly - from the aforementioned contracts;
Provided no interest, right, or fundamental liberty on the part of Data Subject, and requiring the protection of any personal data, trumps the same.

DATA PROCESSING METHODS
The processing of personal data may be performed with the aid of analogue, electronic, or otherwise automated instruments, with methods and procedures strictly related to the pursuit of the foregoing purposes. Company carries out processing directly through parties within its own organisation, or in outsourcing.
Such parties shall process data pursuant to instructions provided by Data Controller, as either authorised persons or processors, and solely in the pursuit of specific purposes as stated herein; or, if independent data controllers, then autonomously.

DATA DISCLOSURE
Personal data - solely for the purposes appearing in point 1 - may be disclosed to:
a) Data Controller employees or associates duly authorised by the same to process data;
b) Credit institutions, service companies for the recording, packaging, transport, and handling of documents, subcontractors tasked with projects or construction, service providers, notaries, attorneys, experts, consultants, collections companies, auditing firms;
c) Entities to whom disclosure is required in compliance with any collective-bargaining agreement (e.g. a labour union) or specific regulatory duties (e.g. police force or other public authority).
The data shall not be disseminated.

DATA SUBJECT RIGHTS
Data-protection regulations (see Art. 12-22 of EU Regulation no. 679/2016) guarantee the right to be advised of data processing, the right to access the data themselves at any time, and to request such data be updated, supplemented, or corrected. Where the criteria established by the law are met, the Data Subject may also exercise the right to have the data deleted, limit their processing, object to processing, to avoid being subject to decisions based solely on automated processing, and the right to data portability.
Should personal-data processing be predicated on Data Subject consent, the Data Subject shall have the right to revoke such consent.
To exercise your rights - and for more detailed information regarding the parties or categories of parties to whom data might be disclosed, or who might have access to the same as data processors or authorised persons - please contact Company’s Data Protection Officer and/or via email at privacy@guarniflon.com.
Should you believe your rights have been infringed upon, you may protect your rights by lodging a complaint with the Data Protection Authority.

DATA RETENTION PERIOD
Personal data shall be retained for so long as is necessary to realise the purposes appearing in point 1 herein; following the achievement of such objectives, the data may be retained until the rights accruing to you and to Data Controller from the legal relationship have lapsed with respect to any facts directly or indirectly related to the purposes themselves.

PROCESSING OF THIRD-PARTY DATA
The vendor is on notice that should it avail itself of any employee or associate (including any subcontractor) to perform services for the benefit of Data Controller, such third party’s data may be processed by Company, acting likewise as Data Controller, for the purposes appearing in subsection 1(b) herein (management of communication with supplier contact persons and delegates). Such processing shall have the same goals, methods, and retention period as the data otherwise described in the instant policy; furthermore, with respect to such processing, data subjects shall have the same rights identified in point 6 herein.
Vendor agrees to properly advise its own employees and associates with respect to such processing, including but not limited to by providing the instant policy to them, and by recording their signature in acknowledgement whereof.
