What is Acryft™?

Acryft™ is an ethylene-methyl methacrylate copolymer (EMMA).
Acryft™ is as easy to process as LDPE and demonstrates higher softness and transparency.

Features of Acryft™

1. Good thermal stability
2. Easy processing same as LDPE
3. Low corrosivity, VOC, and odor with no acid generation
4. Higher level of softness and transparency

Grades

Acryft™ is available in a wide range of MMA content levels and MFR.

The values given are standard values and not to be considered as sales specifications or guaranteed values.

*1：190℃, 21.2N
*2：Test specimen No. 2 at a tensile speed of 500mm/min
*3：Ring & ball method by §6.4
*4：Environmental Stress Cracking Resistance / Bent strip method using IGEPAL CO-630 10% solution

Thermal stability

1. Recyclability

Acryft™ shows no increase in viscosity even during high-temperature processing and can therefore easily be recycled in extrusion processing.

2. Durability in high temperature processing

Comparison of scorched spots on extruder filters after continuous extrusion processing (Acryft™ vs. EVA)

Acryft™ can be applied to long, continuous extrusion processing as it experiences less gelation under high-temperature processing.

Low corrosivity (no acid generation)

Resin samples	20% as co-monomer content
Test method	A resin sheet sample (thickness: 3mm) was put on an iron plate (size: 50×30×3mm) at 280℃ and 100kg/cm2 for 10min. Afterwards, the iron plate was removed from the resin sheet and placed under saturated water vapor at room temperature for 24hrs.

Acryft™ can be used safely for metal contact applications.

Easily peelable from rubber materials

Acryft™ is suitable for rubber wrapping film due to its low adhesion strength to rubber materials.

Resin for film		Acryft™	LDPE	EVA	EEA
Co-monomer content (wt%)		10	-	5	18
Peel strength between film and rubber (g/25mm)	vs. butyl rubber	165	450	480	500
	vs. EPDM rubber	20	700	670	540

Film thickness: 30μm
Pasting conditions (film and rubber): Load 10kgf/(150mm×150mm) at 80℃ for 2hrs
Peeling speed: 300mm/min

VMCPP application

Recommended amount of Acryft™ added to the metallization layer of CPP: 10-20wt%
Suitable grade: WH303-F or WH401-F

Acryft™ (showed in pink circle) is a useful material to improve bonding strength of VMCPP by dosing 10-20wt% to the metallization layer of CPP.

Extrusion lamination properties

Acryft™ shows superb bonding strength with several base layers compared with LDPE thanks to its extrusion lamination properties.

Base layer (substrate)		Al	PET	O-Ny	PE
Processing conditions	Extrusion temp.	310℃	310℃	310℃	300℃
	Corona discharge treatment	No	Yes	Yes	No
Adhesive strength between substrate and laminated resin	Acryft™	3.3	3.1	7.7	> 10
	LDPE	1.2	1.5	2.4	2.8

Unit of adhesive strength in above table: N/25mm

* Layer structure: Substrate//laminated resin(40μm)
* Lamination speed: 80m/min
