I need to source fully printed HVAC duct tape that carries our company logo across the entire roll. The tape must deliver high adhesive strength so it can maintain an airtight seal on galvanized steel and flexible ducting without lifting over time. Scope • Identify manufacturers or converters capable of producing custom-printed HVAC duct tape in standard 48–50 mm widths. • Confirm print method (full-surface logo repeat) and colour fidelity against our supplied vector artwork. • Provide adhesive performance data demonstrating high tack and shear suitable for HVAC applications; temperature and moisture resistance are desirable but not mandatory. • Submit pricing tiers, minimum order quantities, sample lead time, full production lead time, and available sh...

The goal is to formulate a shelf-stable liquid that behaves like cow's/Buffalo's milk when run through standard milk-testing analyzers, yet contains no perishable dairy components. The solution must be tunable so that I can call for any value within these working windows: • Fat: 2.5 % – 12 % • SNF: 6.5 % – 10 % • Protein: 3 % – 6 % Accuracy should match typical calibration-grade samples (±0.05 % for fat, ±0.1 % for SNF and protein) and hold that performance for at least six months at room temperature. Key considerations The mimic has to flow, foam and disperse pigments just as fresh milk does, without clogging or coating optical or ultrasonic sensors. Viscosity, density and dielectric properties therefore need to si...

I’m refining a food formulation that must remain 100 % EU Organic compliant while moving from benchtop trials to a clean, well-documented pilot batch. My top priority is maintaining impeccable hygiene throughout production—recipes, SOPs, and any equipment recommendations must reflect that. Here’s what I need from you: • Review and, if necessary, tweak the current formula so it stays stable and meets EU Organic regulations. • Translate lab-scale quantities into a clear, scalable process flow (ingredient prep, critical control points, hold times, etc.). • Draft concise hygiene SOPs tailored to the proposed equipment line, highlighting surfaces, sanitation cycles, and allergen separation. • Prepare a pilot-batch protocol (yield ≈ 25&ndas...

Potrzebuję wsparcia chemika lub technologa z realnym doświadczeniem w ochronie przed korozją metali. Interesują mnie przede wszystkim powłoki ochronne – receptury tworzone od podstaw. Mile widziana znajomość farb, podkładów epoksydowych, polimerów, poliuretanów czy inhibitorów korozji. Zakres współpracy obejmuje: - Konsultacje łączenia substancji, - Proces łączenia substancji w produkt - Szeroka wiedza dotycząca powłok, farb, polimerów lub tworzyw sztucznych. Liczę na kontakt z chętnymi osobami, będącymi z Lublina, Puław (woj. Lubeslkie) i bliskich okolic. Mocno zafiksowanymi na walkę z korozją.

Looking for health and safety equipment required in a factory using ammonia. The cacdudate should have the relevant experience in Health and Safety inspection and be able to recommend vendors from whom to procure the required equipment. Below are some observations based on safety inspection conducted at the factory 1. Training Operators on operating Ammonia Lines and Valves 2. Adequate Fire Fighting equipment and Operating Instructions in multi language. 3. Showers to protect the workers exposed to toxic and corrosive substances. 4. Safety measures in ammonia storage area to prevent the risk of fire, explosion, or the formation of toxic concentration of ammonia. 5. Effective audible and visible alarm systems in the hazardous ammonia gas process area and storage area to warn of unsafe ope...

I’m building a new skincare brand and need an experienced cosmetologist or formulation chemist to co-create the first collection. The line will cover everyday basics—think gentle cleansers, balanced moisturisers and a lightweight serum—plus a couple of targeted products that tackle acne flare-ups and help minimise tanning-related discolouration. Here’s what I’m after: • Concept-to-lab-ready formulas for each product, complete with percentages, pH targets and preservation systems. • Guidance on actives, botanicals or any other ingredients that will give reliable results; I’m open to both natural/organic extracts and proven chemical actives, so feel free to recommend what works best. • Stability and safety test protocols I can hand stra...

Material Engineer Required – Material Compatibility & Corrosion Control Seeking an experienced Materials Engineer / Corrosion Engineer to support the material selection and corrosion assessment of gas-liquid separation equipment operating in demanding process environments. The successful freelancer will provide engineering support for material compatibility, corrosion control strategies, and recommendations for pressure vessels and separator internals exposed to chemically aggressive process fluids. The engineer will review material compatibility for equipment exposed to one or more of the following process media: * Wet CO₂ * Hot water * Amine-based solvents * Alkaline solvents * Potassium carbonate solutions * Solvent promoters and additives * Solvent degradation...
