Protection built into every plastic
The d2p range adds targeted functional protection — antimicrobial, anti-insect, flame retardant, corrosion inhibition, and more — directly into the polymer at the manufacturing stage. No coatings. No post-processing. No compromise on performance.

Full product range
Eight d2p technologies, one trusted supplier
Each d2p masterbatch technology is engineered to be compounded into the base polymer during production — delivering permanent, certified protection that cannot flake, wash, or wear off.
Antimicrobial
Protect plastics from harmful microorganisms

d2p AM incorporates an EPA-registered, broad-spectrum antimicrobial agent directly into the polymer matrix. It inhibits the growth of bacteria, mould, fungi, and algae on the plastic surface — without leaching or toxic residues.
Key benefits
- ✓Effective against bacteria, mould, fungi, and algae
- ✓Approved for food-contact applications (EU & FDA)
- ✓Durable — protection built into the polymer, not a coating
- ✓Suitable for packaging, healthcare, and consumer goods
Applications
Anti-Insect
Repel insects without pesticides or coatings

d2p AI uses active ingredients embedded in the polymer to deter a wide range of insects including flies, mosquitoes, and beetles. Ideal for applications in agriculture, food storage, and pest-sensitive environments.
Key benefits
- ✓Long-lasting repellent effect built into the plastic
- ✓Non-toxic and safe for use around food and people
- ✓Compatible with standard extrusion and moulding processes
- ✓Can be combined with d2w for biodegradable pest-deterrent films

Anti-Insect — Natural
Mechanical insect control — natural, non-toxic, built into the plastic

A mechanical plastic insecticide masterbatch — sharp, abrasive particles cut through the exoskeleton of insects, causing them to dry out and die. Prevents insects from penetrating packaging, consuming the product, and laying eggs.
Key benefits
- ✓Mechanical mode of action — no chemical pesticides
- ✓Non-poisonous and non-toxic to fish and aquatic invertebrates
- ✓Approved for food contact — FDA (USA) and EFSA (EU)
- ✓Effective against moths, beetles, weevils, cockroaches, bed bugs, fleas, and more
Applications
Flame Retardant
Delay ignition and slow flame spread

d2p FR reduces the flammability of plastics by interrupting the combustion cycle. It can achieve UL-94 ratings and significantly extends the time available for safe evacuation or fire suppression in industrial and construction applications.
Key benefits
- ✓Achieves UL-94 HB to V-0 flame ratings (formulation dependent)
- ✓Halogen-free options available
- ✓Minimal impact on mechanical or optical properties
- ✓Compatible with PP, PE, and engineering thermoplastics
Applications
Ethylene Adsorber
Absorb ethylene gas to extend fresh produce shelf life

d2p EA incorporates ethylene-adsorbing agents directly into the polymer matrix of packaging films and bags. By capturing the ethylene gas emitted naturally by fresh produce, it significantly slows the ripening process and reduces spoilage.
Key benefits
- ✓Actively absorbs ethylene from inside the package
- ✓Extends shelf life of fruits, vegetables, and flowers
- ✓Reduces food waste and supply chain losses
- ✓Certified for direct food contact (EU & FDA compliant)
Applications
Rodent Repellent
Protect infrastructure from rodent damage

d2p RR uses food-safe deterrent compounds to make plastic surfaces unpleasant for rodents to gnaw on. It protects cables, pipes, and agricultural films from damage in warehouses, field installations, and urban infrastructure.
Key benefits
- ✓Reduces chewing damage to cables, pipes, and films
- ✓Safe for humans and non-target wildlife
- ✓Cost-effective alternative to metal sheathing or physical barriers
- ✓Fully embedded — effect does not wash off
Applications
Vapour Corrosion Inhibitor
Protect metal parts from corrosion during storage and transit

d2p VCI releases vapour-phase corrosion inhibitor molecules that form an invisible protective layer on metal surfaces inside the packaging. No oil, grease, or coating required — packaging is clean and ready to use.
Key benefits
- ✓Protects ferrous and non-ferrous metals without contact application
- ✓Eliminates costly degreasing or re-cleaning before use
- ✓Available in film, bag, and sheet formats
- ✓Effective for up to 5 years in correct packaging conditions
Applications
Fragrance / Scent
Add long-lasting fragrance or scent to any plastic product

d2p FS incorporates microencapsulated fragrance compounds directly into the polymer, releasing a controlled, pleasant scent throughout the product's lifetime. Suitable for a wide range of consumer goods, packaging, and industrial applications that benefit from a branded or functional scent.
Key benefits
- ✓Long-lasting scent release embedded in the plastic
- ✓Wide fragrance library — custom scents available on request
- ✓No coating required — fragrance is integral to the product
- ✓Compatible with PE, PP, and engineering plastics
Applications
Unique advantage
Combine d2p with d2w biodegradability
Symphony is the only supplier that can integrate protective performance (d2p) with controlled oxo-biodegradability (d2w) in a single masterbatch technology package — giving manufacturers compliance with both sustainability mandates and functional performance requirements.
